Synthesis and Reactions of Some 4-Chloro-4-alkoxycarbonyl-1,2diaza-1, 3-butadienes.

-A simple two-step preparation of the new title compounds (III), which prove to be stable, versatile and reactive nucleophilic acceptors, is given. α,α-Dimethoxyhydrazone derivatives (V) as well as otherwise hard accessible functionalized pyrazole derivatives (VI) are easily obtained from (III) in high yields under mild reaction conditions. -(ATTANASI, O.
