Sulfur Nitride in Organic Chemistry. 9. The Reaction of Tetrasulfur Tetranitride with Benzyl Ketones. Preparation of 3,4-Disubstituted-1,2,5-thiadiazoles

The reaction of tetrasulfur tetranitride (1) with various aryl and 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.
