Abstract

There is no need for preparing individual reactive species and water as an only by-product seems to be highly attractive. These type reactions have hitherto been achieved using Lewis acids, 2, 3, 4 and 5 Brønsted acids, 6 and iodine 7 in organic solvents. Water is undoubtedly a greener solvent than organic solvents. The salient features of water in organic syntheses, exemplified by acceleration of reactions and enhancement of selectivities, have prompted organic ...
