METHOD OF SYNTHESIS OF N-(DIMETHYLAMINOMETHYLENE)-1,2,4- -TRIAZOLE Russian patent published in 2000 - IPC

Abstract RU 2146673 C1

FIELD: organic chemistry and technology. SUBSTANCE: invention describes the method of synthesis of N-(dimethyl- -aminomethylene)-1,2,4-triazole from 1,2,4-triazole that is subjected for reaction with N,N;N,N--tetramethylmethylenediamine at molar ratio = 1:(1-1.2) in medium of aromatic solvent, in the presence of catalyst taken among transient metal chlorides or acetylacetonates in the amount of 0.01-0.03 mole% with respect to 1,2,4-triazole, at 80-110 C, under atmosphere pressure for 2-4 h. EFFECT: simplified process, increased yield of end substance, improved technology and ecology. 1 tbl, 1 ex
