  Steric and Electronic Parameters Characterizing Bulky and Electron-Rich Dialkylbiarylphosphines

  摘要：

  The steric and electronic properties of several sterically demanding tertiary phosphines (dicyclohexylphosphino)biphenyl (2a), 2-dicyclohexylphosphino-2'-methylbiphenyl (2b), 2-dicyclohexylphosphino-2',6'-dimethoxybiphenyl (2c), 2-dicyclohexylphosphino-2',4',6'-triisopropylbiphenyl (2d), 2-diphenylphosphino-2'-(N,N-dimethylamino)biphenyl (2e), 2-di-tert-butylphosphino-2'-(N,N-dimethylamino)biphenyl (2f), and di(cyclohexyl)phenylphosphine (2g) have been studied [IrCl(cod)(L)] (L = 2a-d) and cis-[IrCl(CO)(2)(L)] (L = 2a-d and 2g). The infrared stretching frequencies of the carbonyl complexes permit an estimation of the ligand donor properties (basicity) and suggest that the donor properties of ligands 2a-d reside between that of 2g and PCy3. The crystal structures of several [IrCl(cod)(L)] (L = 2a-d) and cis-[IrCl(CO)(2)(L)] (L = 2a-d and 2g) complexes are reported and used to quantify the ligand steric parameter.
