“…Inspite of less reaction time in some previously reported methods [ 24 , [36] , [37] , [38] ], the present protocol is more fruitful because earlier reported protocols include harsh reaction conditions, metal-contamination, tiresome process, need work-up for purification, no recyclability of catalyst, less substrate scope, etc. Whereas, the designed pathway has several benefits like reusability of catalyst up to five runs, cost-effective, excellent yields, large substrate scope.…”
