Darst. This thesis describes the application of 2-phosphino-N-aryl-heterocycles as ligands in Pd-catalyzed CC, CN and CO bond forming reactions. Based on prior studies, 2-phosphino-N-arylindoles and -pyrrols were found to form efficient catalysts with Pd-salts in the Sonogashira coupling of (hetero)aryl bromides and the Pd-catalyzed monoarylation of ammonia. The novel imidazole-based phosphines were prepared after a modular synthesis and are stable towards air. They were employed in the Pd-catalyzed phenol synthesis, the Heck-Cassar coupling, and the Pd-catalyzed monoarylation of ammonia. Furthermore, mechanistic studies in the Pd-catalyzed hydroxylation were undertaken. vorgelegt von Christian Torborg Enth. 5 Beitr. aus versch. Ztschr Rostock, Univ., Mathematisch-Naturwiss.
