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.

Great! I'm in the process of converting it to HTML and placing it here:
https://www.thevespiary.org/rhodium/Rhodium/chemistry/nitrostyrene.references.html (https://www.thevespiary.org/rhodium/Rhodium/chemistry/nitrostyrene.references.html)
The nitromethane section is still missing, and I will add it to the document tomorrow and also put
tags around all the square brackets to make the refs more distinct, as in "Part 2" of the nitrobutane section.
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 intended for Rh's HTML?

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