Abstract
Abstract The reaction of tetrasulfur tetranitride (1) with various aryl and alkyl benzyl ketones (2a-o), oxindole (11), benzyl α-pyridyl ketone (12) and α-phenacylpyridine (13) afforded the corresponding 1, 2, 5-thiadiazoles (3a-n, 11 and 14). The scope and limitations of the above reaction were investigated and the evidences suggesting the radical anion mechanism are presented.
