using an ionicliquid [Et3NH] + [BF4]\(^-}_\thinspace }\)as catalyst. All the reactions gave products with high degree of purity and excellent yield (78–93%) within the shorter span of time (20–65 min) than those reactions with conventional methods. The screening of solvents as well as the reuse of ionicliquid has been evaluated. The structure of the products has been elucidated by spectral and analytical
