Synthesis and reactions of chloroazodienes. A new and general synthesis of pyridazines
South, Michael S.,Jakuboski, Terri L.
, p. 5703 - 5706 (1995)
The reaction of dichlorohydrazones with Hunig's base gives 4-chloroazodienes, which were found to combine with a variety of electron rich olefins to yield chloro-substituted tetrahydropyridazines. These chloroazodiene cyclizations are best characterized a
