摘要：

The preparation of (DIPPP)Pd(PR3) and [(DIPPP)(PR3)PdH][OR'] (DIPPP = bis(1,3-diisopropylphosphino)propane; R = Cy, Et; R' = Ar, CF3SO2) is reported. (DIPPP)Pd(PCy3) and [(DIPPP)(PCy3)PdH][CF3SO3] have been structurally characterized. (DIPPP)Pd(PR3) complexes catalyze the reaction of ethylene with carbon monoxide and phenols to give aryl propionates. In situ P-31 NMR experiments have shown that the resting state of the catalyst in these transformations is the binuclear species [C(DIPPP)Pd)(2)(mu -H)(mu -CO)][OPh].
