摘要：

Reaction of Na[MCl4] (M = Pd or Pd) with the azo-containing phosphines Ph2P{1-(4-RC6H4N2)-2-OR'-C10H5} {R = Me (I), NMe2 (II); R' = C(O)Me} affords the complexes [MCl2L2] (1-4) in good yield. Complexes 1-4 have all been fully characterised by elemental analysis, H-1-, C-13{H-1}-, and P-31{H-1}-NMR spectroscopy and UV-visible spectroscopy. The use of 1 in the Heck reaction has been investigated and shown to effect up to 1000 turnovers. (C) 1999 Elsevier Science S.A. All rights reserved.
