Abstract

ck-[P&R,] (L= Me,SO or Me& R = Me or Ph) species react with N,N’-disubstituted dithioxamides HZ-Rf2-DTO (R’ = methyl, benzyl, n-butyl) leading to a new class of organoplatinum compounds of general formula [PtL(R)(H-R’,-DTO)] (1). These are the first reported organometallic complexes containing an S,S’ Pt chelated rubeanate. The new compounds react with some neutral ligands L’ (L’=carbon monoxide, phosphines and thioureas) giving [PtL’(R)(H-R’,-DTO)] (2) products, which are totally unreactive toward nitrogen bases such as amines, pyridines and anilines. The compound truns-[Pt(Me,SO),MeCl] reacts with H2-bz2-DTO forming the contact ion pair {Pt(Me,SO)Me(H,-bz,-DTO)+,(Cl-)} (3); this is a non-isolable species since the Pt-CH, bond is cleaved by acidic hydrogens of the coordinated neutral dithioxamide leading to the formation of methane and [Pt(Me,SO)Cl(H-bz,-DTO)] (4). A structure for the tight ion pair {Pt(Me,SO)Me(H,-bz,-DTO)+,(Cl-)} is proposed in which the coordinated neutral dithioxamide acts as an anion binding agent.
