Synthesis of 3-alkyl-4-aryl- and 3,4-diaryl-1,2,5-thiadiazoles via palladium-catalyzed cross-coupling reaction

4-Substituted 3-aryl-1,2,5-thiadiazoles were synthesized by palladium-catalyzed cross-coupling reaction of arylstannane with easily available 4-substituted 3-halogeno- and 3-trifluoromethylsulfonyloxy-1,2,5-thiadiazoles.

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.
