Abstract

Phosphorus ylide complexes [PdBr2{Ph2P(CH2)nPPh2CHC(O)R}](n= 1 or 2; R = Me, Ph, or OEt), and mixed sulphur and phosphorus ylide complexes [Pd{(CH2)2S(O)Me}{Ph2P(CH2)n-PPh2CHC(O)R}]I, have been synthesized by the phase-transfer technique. The presence of the phase-transfer catalyst has only a marginal effect in the preparation of phosphorus ylide-containing complexes. The mixed ylide compounds have both a chelated double sulphur ylide and a C,P-chelated phosphorus ylide. A mixed-ylide complex [Pd{(CH2)2S(O)Me}{Ph2PCH2-PPh2CHC(O)Ph}]I·CH2Cl2·H2O has been investigated by means of X-ray crystallography. The Pd–C bond length of 2.183 5)Å for the phosphorus ylide co-ordination is longer than that for the sulphur ylide co-ordination [2.094(3)Å(average)].
