Synthesis of Ketones (an interactive tutorial on the Claisen reaction and
synthesis of ketones from beta-ketoesters.)
I got 11 wrong answers in the 9 parts of the 3 hour online tutorial, mainly because some maniac was constantly talking to me. Junks are a menace.
This tutorial requires the Flash 4 plug-in:
To go through the whole tutorial should take a total of a couple of hours after which you should understand the following topics:
-- Using beta-ketoacids in the synthesis of ketones.
-- Mechanism of the Claisen reaction, the reversibility of the Claisen reaction and the choice of base.
-- The Dieckmann condensation and the position of equilibrium in the condensation.
-- The reverse Claisen, which can be used to give acids.
-- The easy decarboxylation of beta-ketoacids.
-- Retrosynthesis applied to ketones which are synthesised from beta-ketoacids.

You can click on the experiments to launch interactive teaching practicals.
I advise to download MDL's FREE chemical structure visualization plug-in for Windows and Macintosh, to be able to enjoy the full experience of all the links on this page:  CHIME.
And then (you already downloaded Flash 4 plug-in? See above) you should

Remember the first time you ever boiled water? You will certainly have noticed how the steam formed running droplets, i.e. condensed, on nearby surfaces. This was your first distillation. In the following report you will learn how to carry out distillations more scientific.
Every substance has its own physical characteristics such as melting point and boiling point. The determination of the melting point is a simple and fast method which indicates roughly the purity of the substance.
World-wide around 200,000 rotary evaporators and just as many static glass systems are in use. Taking a distillate loss rate of 10%, this adds up to an immense amount of 160,000 litres of solvent polluting the laboratory air and the environment every day. What are the reasons of these solvent losses?
A rotary evaporator is a specially designed instrument for the evaporation of solvent (single-stage or straight distillation) under vacuum. The evaporator consists of a heating bath with a rotating flask, where the liquid is distributed as a thin film over the hot glass surface and evaporates easily.
Are you working with a rotary evaporator? Vacuum generation and vacuum control would optimize the operation mode. How are these instruments used?
When working with combustible materials, the presence of an ignition source entails the danger of an explosion. Its effect is uncontrollable, it might endanger people and destroy material values. Electric appliances and tools used in dangerous areas, are potential sources of ignition. It is important to take measures against the risk of ignition.
THERE ARE a few more TRAINING FILES there.
BTW, this is a real ROTARY EVAPORATOR:

Distil up to 20 litres of solvent efficiently and gently.
The new Büchi Rotavapor® R-220 is designed for rapid, efficient evaporation of sample volumes up to 20 litres. Its broad temperature range from +20° C to +180° C opens up a wide range of applications and ist modular design makes it possible to fully adapt the Rotavapor® to your individual needs. Its superior cost-to-benefit ratio also makes the R-220 a most attractive economic investment.
This is the "small" one:

The top model, which has a display module for vapour temperature and the rotation speed of the flask plus integral Vacuum Controller V-805.
Abbrevations of chemical compounds. If you know an abbrevation like THF or DMSO and want to find the chemical compound then have a look here.

Go to right away this instant - it is a great information resource of collected and sorted abstracts, one could say that it is kind of like the Neuroscience/Neuropharmacology answer to my own Psychoactive Synthesis archive - it is also a one-man project.

From the description of the site: is a unique project involving research from the fields of neuroscience, neuropsychology, psychiatry, genetics, and others. The sole creator of is Shawn Thomas. By compiling and sorting dozens of abstracts on specific topics, I seek to introduce a context to research articles that cannot easily be obtained while reading individual abstracts. When an abstract is viewed in context, I believe that an individual has a greater chance of understanding that information in relation to similar research produced by other sources. is in part an experiment to determine the usefulness of using HTML to organize and present large amounts of scientific information through the medium of the Internet.

Many of the pages on may also serve as general reviews on various topics. Because the details of research efforts are often difficult to condense into just a few words, abstract compilations may offer more comprehensive reviews of complex subjects like the genetics of bipolar disorder. Unlike published reviews, pages on may be updated to reflect the consistently changing nature of the neurosciences. I do not intend to attempt to include every possible article on each page; PubMed is available to those who demand such a database.

The intended audience of this site includes anyone interested in the material chosen for the site. I hope that the research community will embrace and the concept behind it.

STRIP (REEL-TO-REEL) PLATING :  Reel-to-reel (moving strip) plating.

I'm thinking of a copper bandolier which can be plated with Pd or Pt. In many wackers you could offer the cut pieces of copper strip plated with your catalyst of choice to solute in acidic environment, leaving the Pd or Pt as the catalyst behind.
The deposit builds up from zero thickness at the strip entry into the cell, to the final thickness of 34 µm at the strip exit (upper left), for a strip velocity of 0.3 m/s.(30 cm per SECOND!)
This technique will get you :
Micro-scale roughness and dendrites formation on resistive moving strip.
Detailed roughness build-up on sub mm and micron scales RRW (reel-to reel)

Perhaps even Kevlar or any strong carbon strip material could be found to be plated!  LT/

      Great Course in Inorganic/Organometallic Chem
(Rated as: excellent)


Inorganic chemistry covers the whole periodic table and in a way includes organic chemistry as a special case.

Inorganic compounds hold most world records and can display unique physical anc chemical properties, structures, reactivities and bonding situations that are not encountered in organic chemistry. Or, to state it shamelessly honest:
"In inorganic chemistry everything is super"
Prof. W. Beck, Munich, 1986

Example of entertaining "fact boxes" interspersed in the text:


For a fascinating account of fulminates see: F. Kurzer, J. Chem Ed. 77, 851-857 (2000) (

Fulminates have played an important role in the history of chemistry. Although mercury fulinate was possibly already obtained by the Dutch scientist Cornelius Drebbel (1572-1634), the first well documented discovery took place in the laboratory Johannes Kunckel (1630-1703).

The reason for the early discovery of mercury fulminate are due to its ease of formation: mercury or mercury oxide dissolved in nitric acid and then treated with ethanol under heating gives a mercury fulminate, Hg[CNO]2 as voluminous white precipitate. The mechanism of this reaction seems to be obscure.

"I once dissolved silver and mercury together in aqua fortis, and, having added spiritus vini,
set the vessel aside in the stable. When by the next day, its temperature had risen, there occured
such a thunder clap, that the groom thought someone had shot athim through the window, or that the
very devil had appeared in the stable. But I realized that it was my experiment that had exploded."

- Johannes Kunckel (1716)

Mercury fulminate was a crucial ingredient in Alfred Nobel's invention of dynamite (which layed the financial foundation for the Nobel prize). Soaking up nitroglicerine in kieselguhr had removed its shock sensitivity, but also required the introduction of a primer charge. Mercury fulminate worked very well and A. Nobel patented this discovery. It must be noted that mercury fulminate is unsuitable as a bulk explosive due to its high detonation velocity ("brisance" military testing led to gun barrels split in half....).

Example of many useful experimental procedures:

Ethyl 3-aminopropanoate  (5)
Carrie, R., Bull. Chem. Soc. Fr. 815 (1985)

To a 1 M solution of 4 in THF (from the bromo ester with NaN3 in DMSO) was added a molar equivalent of Ph3P, 1.5 equiv of water and a boiling chip (N2 evolution). After 8 h at 200°C and evaporation, the residue was treated with Et2O-hexane and Ph3P=O was filtered. This process was repeated and 5 was distilled at 40-45°C/10.5 mmHg (83%).

Historical footnotes - carbene [ :CH2 ] was first ever mentioned in print in 1944 by D. Duck:
