- W2012258594 abstract "Treatment of [Pt(C2H4)(PPh3)2] or [Pt(PPh3)4] with 3-chloro-2-chloromethylprop-1-ene (1) and KPF6 at room temperature affords [Pt{η3-CH2C(CH2Cl)CH2}(PPh3)2][PF6](3a). The carbon–chlorine bond in (3a) is reactive and treatment of (3a) with the Lewis bases L (L = PPh3, NEt3, or pyridine) in the presence of KPF6 affords the dicationic salts [Pt{η3-CH2C(CH2L)CH2}(PPh3)2][PF6]2. Reaction of (3a) with lithium bromide gives [Pt{η3-CH2C(CH2Br)CH2}(PPh3)2][PF6]. A phosphonium salt [Pt{σ-CH2C(CH2PPh3)CH2}{P(OMe)3}3][PF6]2 is formed on addition of trimethyl phosphite and KPF6 to (3a). Evidence for the activation of the carbon–chlorine bond in (3a) is provided by the much slower reaction of (1) with PPh3 and KPF6 to give [CH2C(CH2Cl)(CH2PPh3)][PF6] and triethylamine and KPF6 with [Pt{σ-CH2C(CH2)CH2Cl}(S2CNMe2)(PPh3)] to give [Pt{σ-CH2C(CH2)CH2NEt3}(S2CNMe2)(PPh3)][PF6]. A bridging trimethylenemethane complex [Pt{η3-CH2C[CH2PtCl(PPh3)2]CH2}(PPh3)2][PF6] is formed in the reaction of (3a) with [Pt(C2H4)(PPh3)2] and KPF6. N.m.r. data for the complexes are reported, the assignments of the syn and anti protons in [Pt{η3-CH2C(CH2PPh3)CH2}(PPh3)2][PF6]2 being confirmed by a proton–proton nuclear Overhauser enhancement difference experiment." @default.
