Internally consistent assignments of the 31P- NMR parameters of the complexes CR')(PPh3)2> are proposed, based on the premise that the magnitude of 1J(PtP) depends mainly on the nature of the moiety CR trans to P.For a given R, 2J(PP) correlates with 1J(PtP) for the bond trans to CR.The alkynes PhCCSnEt3, PhCCSnPh3, Me3SiCCCl, Me3SiCCBr, Et3SiCCI and MeCCI undergo oxidative addition reactions with ; the intermediate alkyne complex was detected for PhCCSnEt3, Me3SiCCCl and Me3CCBr.The triyne Me(CC)3Me forms platinum(0) complexes by coordination with the central or terminal CC bond and appears also to give a platinum(II) complex by oxidative addition.
