摘要：

Two new cationic rhodium(I) complexes containing a phosphino amino alcohol ligand and a methoxy amino phosphine, respectively, have been prepared. According to IR and NMR data the ligands are P,N-bonded and coordination of the hydroxy or the methoxy group to the metal does not take place. The complexes were applied to the hydroformylation of styrene and displayed a quantitative chemoselectivity for aldehydes with a very good branched:linear ratio. The reaction rate is higher using the complex possessing the methoxy group as opposed to the hydroxy group. (C) 1999 Elsevier Science S.A. All rights reserved.
