摘要：

Thiocyanation of various aromatic and heteroaromatic compounds has been studied using Zeolite H-SDUSY Powder (CBV720) as catalyst and ammonium thiocyanate (NH4SCN) as thiocyanation reagent in acetonitrile medium. Reactions afforded good yields of products under stirred conditions at reflux temperature. Reactions underwent enhancements under sonication (using an ultrasonic probe of 24kHz frequency) and microwave irradiation. The use of ultrasound decreased the reaction times from (7-12h) to few minutes (70-150min). The use of microwave irradiation much more effectively enhanced the reaction rates than sonicated and conventional protocols used in this study.
