%0 Book %T Synthetic studies of benzodithiophenes, benzodithiazoles, benzopyranones and chemoselective palladium(0)-catalyzed cross coupling reactions of brominated naphthalenes, benzothiophenes and naphthaquinones %A Hassan, Zahid %D 2011 %G English %F 73465264X %O vorgelegt von Zahid Hassan %O Rostock, Univ., Mathematisch-Naturwiss. Fak., Diss., 2012 %X 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. %L 35.69 %9 theses %9 Text %9 Hochschulschrift %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0046-2 %U http://rosdok.uni-rostock.de/resolve?urn=urn:nbn:de:gbv:28-diss2012-0046-2&pdf %U http://nbn-resolving.de/urn:nbn:de:gbv:28-diss2012-0046-2
