摘要

The reaction of the p-tolyl (or phenyl) sulfonylhydrazones of some 2-(alkenyloxy) benzaldehydes with lead tetraacetate leads, via the nitrile imide intermediates, Ar–\ overset+ C= N–\ overset− N–SO 2–C 6 H 4–Xp, to intramolecular 1, 3-dipolar cycloadducts and 1- acetyl-2-aroyl-1-p-tolyl (or phenyl) sulfonyl hydrazines in 20–65% and 7–70% yields respectively, while the intermolecular reactions of the benzaldehyde p- ...
