ВЗАЄМОДІЯ ПРОПЕНІЛЬНИХ ПОХІДНИХ 1,2,4-ТРИАЗОЛУ З 4-АЛКОКСИФЕНІЛТЕЛУРТРИХЛОРИДАМИ

Abstract

The interaction of unsaturated derivatives of 1,2,4-triazole with 4-alcoxyphenyltellurium trichlorides had been studied. New tellurium-fused heterocycles was received. The structure of synthesized compounds was proved by NMR. 4-Alcoxyphenyltellurium trichlorides used as electrophilic reagents in reactions with propenyl derivatives of 1,2,4-triazole. It has been established that the interaction of 5-(2-hydroxyphenyl)-4- prop-2-en-1-yl-1,2,4-triazole-3-thione with 4-alcoxyphenyltellurium trichlorides leads to annulation of the thiazoline ring forming the structure of 3-(4-hidroxyphenyl)-6-(4-alcoxyphenyldichlorotelluromethyl)-[ 1,3]thiazolo[2,3-c][1,2,4]triazole whereas 3-(2-methylprop-2-en-1-yl)thio-4,5-diphenyl- 1,2,4-triazole forms molecular complexes with electrophiles in the ratio of 1:1.
