Abstract
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. Similar experiments at controlled temperature (25 ± 1° C) resulted in comparable yields, showing the promotional role of ultrasound irradiation in the progress of the reaction.
