Abstract: | cis-PtCl(CH2CN)(PPh3)2 was obtained by the reaction of Pt(PPh3)4 with ClCH2CN in acetone. A solution of Pt(PPh3)4 and ClCH2CN in benzene was heated under reflux to give trans-PtCl(CH2CN)(PPh3)2. The reaction of the trans-isomer with Br?, I?, Ph2PCH2CH2 PPh2, Ph2PCH2CH2AsPh2 and cisPh2PCHCHPPh2 has been examined. The trans-influence of a ligand trans to the CH2CN group seems to be indicated by the 2J(PtH) of the CH2CN protons. The τ values of trans-PtX(CH2CN)(PPh3)2 and PtX(CH2 CN)(PP) (X = Cl, Br, I) are related by a linear function. |
