A direct, one pot synthesis of an ellagic acid salt was achieved at room temperature by dimerization of ethyl gallate using N,N-dimethylammonium N′,N′-dimethylcarbamate, a distillable ionic liquid, as solvent.
An efficient, simple, and environmentally benign method for the synthesis of novel sulfanyl tetrazoles has been achieved by one-pot three-component reaction of phenacyl bromides/3-(2-bromoacetyl)coumarins with KSCN and NaN3using [Bmim]BF4ionic liquid. It could be reused and recycled for four runs without significant loss of product yield.
