Kinetic and Mechanistic Study of Bromination of Benzofuran Scaffolds

It is difficult to imagine the synthesis without organobromides. It has been widely used as reactive intermediates and as a versatile synthons in various organic syntheses. -Bromination of carbonyl compound is an important reaction in organic synthesis; as the resulting -bromo-ketones are used in the synthesis of variety of bioactive molecules. Clinically, physiologically important and widely used benzofuran derivatives can be obtained from -bromo carbonyl compounds. In recent past, organic Quaternary Ammonium tribromide (QATBs) have been reported to be crystalline, highly efficient, selective, easy to transport, handling and storage; maintain the desired stoichiometry and Ecofriendly protocol for Bromination. Considering the importance of -bromo synthetic derivatives of benzofuran moiety and Quaternary Ammonium tribromide (QATBs) we have used efficient and environmentally benign protocol phenyl trimethyl ammonium tribromide (PTT) for -Bromination of various benzofuran scaffolds.In view of this systematic kinetics and mechanistic aspects for the Bromination of benzofuran compounds and the synthesis of various bromoacetyl benzofuran scaffold have been described in this book.
