Abstract
Treatment of bis(cyclo-octa-1,5-diene)platinum with 2 molar equivalents of tricyclohexylphosphine affords two-co-ordinate bis(tricyclohexylphosphine)platinum. The complex [Pt(PMeBut 2)2] may be obtained in the same manner but is markedly less stable. Bis(tricyclohexylphosphine)platinum reacts with hydrogen to give trans-[PtH2{P(C6H11)3}2] and with a series of compounds RH, containing active hydrogen, to afford hydrides trans-[PtH(R){P(C6H1l)3}2](R = C6F5, 1,3,5-C6F3H2, 1,3-C6F2H3, C6F5O, PhO, C6F5NH, and C4H4N). Tris(triethylphosphine)platinum is less reactive towards some of these substrates but with pentafluorobenzene yields trans-[PtH(C6F5)(PEt3)2]. Chlorobenzene and [Pt{P(C6H11)3}2] afford trans-[PtCl(Ph){P(C6H11)3}2].Keywords
