  Claimed is a method involving dehydrogenative silylation of aromatic compounds under Rh-catalysis to give an arylalkoxysilane. The method includes the steps of: 1) combining conditions appropriate to form the arylalkoxysilane, starting materials including A) an alkoxysilane having at least one silicon bonded hydrogen atom per molecule; (I) B) an aromatic compound having a carbon-hydrogen bond; and C) a rhodium bisphospholane catalyst. Additional starting materials such as D) a hydrogen acceptor and/or E) a solvent may be added during step 1). The method may further include 2) recovering the arylalkoxysilane. In a preferred embodiment the Rhodium bisphospholane catalyst is of type (II).
• Synthesis of Enantiopure 1-r-Alkyl-2-c,5-t-Diphenylphospholanes and Phospholanium Salts through Direct Alkylation of Phospholane

  Chiral enantiopure 1-alkyl-2,5-diphenylphospholanium salts were obtained in one step through alkylation of phospholane with alkyl triflates. The resulting air-stable phosphonium salts are electron-rich trialkylphosphane precursor ligands for transition metals, and they offer a convenient route toward chiral quaternary phosphonium salts as phase-transfer agents.(© Wiley-VCH Verlag GmbH & Co.
