Abstract

The reaction of several tertiary amine functionalised phosphines with [Pt(COD)Cl-2] has been studied. Reactions with ratios of L:Pt = 2 proceeded cleanly to give either cis or trans complexes depending on the cone angle of the phosphines. The trans complexes could also be prepared by reaction with Zeise's salt. Reactions of [Pt(COD)Cl-2] with L:Pt = 1 are less straightforward, and a mixture of cis and trans monodentate complexes, and in one example, a chelate complex have been isolated. The X-ray crystal structures of [PtCl2(eta(2)-(Pr2PN)-Pr-i(Me)CH2CH2NMe2)] and a monodentate complex [trans-PtCl2(eta(1)-(Pr2PNH)-Pr-i-c-NC5H10)(2)] are reported. (C) 2002 Elsevier Science Ltd.
