Sažetak
Reactions of hydrazones of heterocyclic aldehydes with lead
tetraacetate in the presence or absence of dienophiles are described.
We have found that during the reaction with lead tetraacetate the
formed intermediate nitrilimines react preferentially with the acetate
ion and not with the acetylenic dienophile. An exception is
acrylonitrile which formed the cycloadduct. If the structure of the
intermediate nitrilimine is such that a dipolar cycloaddit~on, involving
the pyridine ring nitrogen, is possible, triazolopyridines are
formed.
