Abstract
Abstract The microwave assisted one pot efficient conversion of ketones into respective amides has been achieved by utilization of environmentally benign catalytic system tailored by tropylium tetrafluoroborate (Tp + BF − 4 ) and 1,1,3,3‐tetramethylguanidinium tetrafluoroborate [TMG][BF 4 ]. The mild reaction conditions, shorter reaction time, and affordable catalytic system are the key points that highlight the importance. The high product yield and ease of recycling impacts the successful product conversion.
