      o-nitrostyrene reference compilation
(Rated as: good read)
 Bookmark   

What follows is a compilation of omega-nitrostyrene syntheses taken from Houben-Weyl. There are 5 threads (forum does not accept post with more than 10000 chars, so I split the references up in the most convenient way):

- benzaldehydes with nitromethane (pt 1 + 2)
- benzaldehydes with nitroethane
- benzaldehydes with nitropropane
- benzaldehydes with nitrobutane

Reference: Houben-Weyl, Methoden der organischen Chemie. Band X/1, Stickstoffverbindungen I, Teil I, pp 342-357

The "PARTS" agree with different pages from H-W. Hence, many references are mentioned several times.

      I didn't know Houben Weyl could be that useful...  Bookmark   

Great! I'm in the process of converting it to HTML and placing it here: ../rhodium/chemistry /nitrostyrene.references.html

The nitromethane section is still missing, and I will add it to the document tomorrow and also put <strong> tags around all the square brackets to make the refs more distinct, as in "Part 2" of the nitrobutane section.

      Once you know...  Bookmark   

Once you know how to deal with the Houben-Weyl, it is one of the most valuable works I'm aware of, chemistry wise. It contains many "general procedures", but what I find most interesting is the fact that it gives a good overview of reaction possibilities. For instance, the reduction of amines. Houben-Weyl doesn't list that many direct amphetamine-related reductions, but it gives a very good overview of what functional groups can be reduced to amines, and what kind of chemicals can be used to achieve that reduction. As such, I have often found it a very good starting point.

the 'strong' tags should be used in place of 'b' at the hive?  or does it really matter?

Hmmm, isn't <strong> intended for Rh's HTML?

Yup, I'm talking about my own HTML, the Hive markup only supports the [b] tag at the moment.
