FVP OF BIS- AND TRIS-(PYRAZOL-1-YL)METHANE. A RADICAL REACTION

Flash vacuum pyrolysis of bis- and tris-(pyrazol-1-yl) methane was carried out.Alpha, gamma and radical eliminations were considered.The products actually formed correspond to a radical reaction.In the case of bis-(pyrazol-1-yl)methane, working at higher temperatures, pyrimidine was obtained.This compound is formed by rearrangement of a PzCH2. radical.

N-Polyazolylmethanes. 1. Synthesis and NMR Study of N,N'-Diazolylmethanes

Thirteen N,N'-diazolylmethanes, including derivatives of pyrazole, imidazole, 1,2,4-triazole, benzimidazole and indazole were prepared by reaction of azoles with methylene chloride under phase transfer catalysis conditions.The relative amounts of isomeric mixtures obtained with 'asymmetric' azoles or with equimolar mixtures of azoles are compared with literature results on monoalkylation of azoles.Proton and carbon-13 nmr spectra of the N,N'-diazolylmethanes are discussed.
