Abstract: | Acylation of some substituted 1,2,4-triazole-3-thiones in the presence of triethylamine gives N-substituted derivatives. S-Substituted derivatives, which are readily transacylated to the N-substituted derivatives on heating, are formed in the case of 4-phenyltriazolethiones in alkaline media. In the case of 4-allyltriazolethiones acylation in alkaline media gives only the N-substituted derivatives. Bromination of the acyl derivatives gives the disulfides. |
