A novel structural rearrangement reaction of dialkylated derivatives of [Pt2(μ-S)2(PPh3)4] involving Pt-C bond formation

Reaction of [Pt2(μ-S)2(PPh3) 4] with the dialkylating agents ClCH2C(O)CH2Cl or ClCH2C(NNHC(O)NH2)CH2Cl gives the dicationic di-μ-thiolate complexes [Pt2{μ-SCH2C(O)CH 2S)(PPh3)4]2+ or [Pt 2{μ-SCH2C(NNHC(O)NH2)CH2S} (PPh3)4]2+, isolated as BPh4 - salts and characterised by ESI mass spectrometry, NMR spectroscopy and single-crystal X-ray crystallography. Treatment of the complex [Pt 2{μ-SCH2C(O)CH2S)(PPh3) 4]2+, which contains a [6.6.4] bicyclic system, with hydroxide ions results in deprotonation of a CH2 group and rearrangement of the resulting monocation, giving [Pt2(μ-SCH 2C(O)CHS}(PPh3)4]+, isolated as its PF6- salt. An X-ray structure determination shows the complex to have a novel rearranged [6.5.5] bicyclic system containing a Pt-S-Pt-S-C five-membered ring with a Pt-C bond. The alkyl ligand has a high trans-influence, manifest in a long trans Pt-P bond and small 1J(PtP) coupling constant to the trans PPh3 ligand. Reaction of [Pt 2(μ-S)2(PPh3)4] with the 2,4-dinitrophenylhydrazone derivative of 1,3-dichloroacetone leads to the closely related complex [Pt2{μ-SCH2C(NNHAr)CHS} (PPh3)3Cl] [Ar = C6H3(NO 2)2] in which a PPh3 ligand is substituted by a chloride.
