Article abstract of DOI:10.1039/DT9900002509

Phosphorus ylide complexes (n = 1 or 2; R = Me, Ph, or OEt), and mixed sulphur and phosphorus ylide complexes 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 I*CH2Cl2*H2O has been investigated by means of X-ray crystallography.The Pd-C bond length of 2.183(5) Angstroem for the phosphorus ylide co-ordinating is longer than that for the sulphur ylide co-ordination <2.094(3) Angstroem (average)>.
