Nitrosation and Hydrolysis Studies of some Thiazole-4-acetic Esters
Campaigne, E.,Selby, T. P.
, p. 1249 - 1253 (2007/10/02)
Nitrosation of hydrazino substituted thiazole-4-acetates has been shown to occur on the ring, rather than the α-methylene carbon, as previously reported.Thus nitrosation of ethyl 2-isopropylidenehydrazono-, 2-benzylidenehydrazono-, 2-(2-benzoylhydrazino)-
