A synthesis of 4-amino-1-azadienes 1 by addition of Zn-enolates of Schiff bases to nitriles is described.This method improves the yields achieved by the former one using AlCl3.Key words: Synthesis; 4-amino-1-azadienes; Zn-enolates.
An Unambiguous Synthesis of Pyrazoles by Sulphur Extrusion from 1,2,6-Thiadiazines

Di-imines (1) react with thionyl chloride and sulphur monochloride and dichloride giving different 1,2,6-thiadiazine S-oxides (3) and 1,2,6-thiadiazines (4), respectively.These last two compounds lead, by heating, to pyrazoles (6) via thermal extrusion of
