Ultrasound-mediated willgerodt-kindler reactions: Non-thermal synthesis of thioacetamides

Mojtahedi, Mohammad M.,Alishiri, Tooba,Abaee, M. Saeed

experimental part, p. 1910 - 1915 (2011/10/08)

Non-thermal, solvent-free condensation of several aryl methyl ketones with amines and elemental sulfur is efficiently conducted using ultrasonic irradiation within short time periods. Consequently, various thioacetamides are conveniently synthesized. Simi
