Use of 1-[(methylthio)thiocarbonylmethyl]pyridinium iodide as the starting material for the synthesis of 1-heteroarylmethylpyridinium salts
Abstract
Reactions of 1-[(methylthio)thiocarbonylmethyl]pyridinium iodide with hydrazine derivatives and o-aminophenols gave 1-heteroarylmethylpyridinium salts derived from 1,3,4-thiadiazole and 1,3-benzazole, under mild conditions.
