Some (η1-allyl)(aryl)platinum(II) complexes of the type Pt(η1-CH2CR=CH2)(Ar)(diphos) (R = H, Me; Ar = C6F5, C6H3Cl2-2,5; diphos = Ph2PCH2CH2PPh2, (p-tol)2PCH2CH2P(p-tol)2) have been prepared from the corresponding η3-allyl complexes Pt(η3-CH2CRCH2)(Ar)-(PPh3) and diphosphines. 1H NMR spectra of the 2,5-dichtorophenyl analogues were interpreted by occurrence of a restricted rotation of the aryl group about the Pt-C-(Ar) bond. NOE experiments on the CH2CMe=CH2 derivatives suggested the occurrence of one dominant rotamer with regard to rotation about the C(α)-C(β) bond where the CH2=C(β)-C(α) plane is nearly perpendicular to the Pt-C(α)-C(β) plane. Reactions of tetracyanoethylene with the η1-CH2CH=CH2 analogues afforded formal [2 + 3] cycloadducts, whereas the reactions with the η1-CH2CMe=CH2 analogues led to formation of linear adducts containing a PtC(CN)2C(CN)2CH2CMe=CH2 linkage.
