摘要
The water-soluble phosphine ligands, 1,3,5-triaza-7-phosphatricyclo [3.3.1.1(3,7)]decane (tpa) and 1-alkyl-1-azonia-3,5-diaza-7-phosphatricyclo[3.3.1.1(3,7)]decane iodides (Rtpa(+)I(-)), with alkyl=methyl(mtpa(+)I(-)), ethyl (etpa(+)I(-)) and n-propyl, (ptpa(+)I(-)), and mtpa(+)Cl(-) react with [Rh2Cl2(CO)(4)] giving the rhodium(I) complexes [RhCl(CO)(tpa)(2)], [RhI(CO)(Rtpa(+)I(-))(2)], [RhCl(CO) (mtpa(+)Cl(-))(3)] and [RhI(CO)(Rtpa(+)I(-))(3)]. The properties and reactivities of the complexes have been investigated using H-1 and (PNMR)-P-31 and IR spectroscopies, The five-coordinate complexes in solutions show dynamic properties. The complexes are catalysts of the water-gas shift reaction, the hydrogenation of C=C and C=O bonds, the hydroformylation of alkenes and the isomerization of unsaturated compounds, Copyright (C) 1999 John Wiley & Sons, Ltd.
