TY - BOOK AU - Hassan, Zahid PY - 2011 DA - 2011// TI - Synthetic studies of benzodithiophenes, benzodithiazoles, benzopyranones and chemoselective palladium(0)-catalyzed cross coupling reactions of brominated naphthalenes, benzothiophenes and naphthaquinones AB - This PhD dissertation includes the synthetic studies of novel heterocycles like benzodithiophenes, benzodithiazoles and benzothieno-chromenones. A comprehensive protocol for such oxidative reactions and mechanistic studies of their cyclization pattern were undertaken. Furthermore, Pd(0) catalyzed chemoselective coupling reactions of brominated benzothiophenes, naphthalenes and naphthaquinones afforded a variety of mono, di and polyarenes. These reactions generally proceed with excellent chemoselectivity in favour of bromide group (Br > OTf) in all cases.
