Since the unsaturated linkages in p-nitrostyrene2 and 2-vinylpyridine3 resemble simple unsaturated carbonyl compounds in their electrophilic character, it was of interest to investigate the Meenvein reaction with these compounds. Brunner and Kustatscher4 have reported that styrene and a, B-dimethylstyrene react with diazotized aniline, p- methoxyaniline, p-chloroaniline and p-nitroaniline to yield the corresponding stilbenes in ...
