摘要：

Complexation of the diphenylphosphinomethylated dendrimer DAB-dendr-[N(CH2PPh2)(2)](16) with PdCl2(PhCN)(2) gave a dendrimer-bound PdCl2 complex. The dendritic Pd complex showed high catalytic activity for the selective hydrogenation of conjugated dienes to monoenes under mild reaction conditions. The catalytic activity of the dendritic Pd complex was higher than that of the corresponding low-molecular weight complex [PhN(CH2PPh2)(2)PdCl2]. The dendritic catalyst was easily recovered from reaction mixtures and could be reused without any loss of the activity. (C) 1999 Elsevier Science B.V. All rights reserved.
