Process for the isomerization of symmetric triazoles to unsymmetric triazoles.

摘要

Symmetric 4H-1,2,4-triazoles are isomerized to the corresponding 1H-1,2,4-triazoles in the presence of an isomerizing agent consisting of an organic halide or epoxide. This process represents a useful method for the recovery of antifungal, antimycotic or microbicidal 1H-1,2,4-triazoles by the isomerization of the unwanted 4H-1,2,4-triazole by-product formed during their preparation.
