Popis:	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.
