Butler, Richard N. published the artcileDetection of a metalo intermediate and geometrical isomerizations in an oxidative cyclization of a heterocyclic hydrazone with mercury(II) acetate, Name: 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Journal of the Chemical Society, Chemical Communications (1981), 376-7, database is CAplus.
Oxidative cyclization of the (E)-hydrazone I on treatment with Hg(OAc)2 (AcOH, 70°, 16 h) gave 37% II, via the (Z)-intermediate III. The reaction mechanism, which involves a series of cis-trans isomerizations, is discussed.
Journal of the Chemical Society, Chemical Communications published new progress about 2215-33-0. 2215-33-0 belongs to pyridine-derivatives, auxiliary class Pyridine,Amine, name is 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, and the molecular formula is C11H10N4, Name: 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine.
