  The reaction chemistry of 2- and 3-aminoalkanethiols with [PtMe3I]4: a new example of the structural diversity of metal thiolates

  摘要：

  The reaction of substitution of iodine in [PtMe3I](4) by 2- and 3-aminoalkanethiols, at several metal to ligand ratios and various reaction conditions in organic solvents, proceeds differently depending mainly on the aminoalkanethiol nature. The substitution by 2-diethylaminoethanethiol has led to a partial replacement of iodine affording the complexes [(PtMe3)(4)(mu-I){mu-S(CH2)(2)NEt2}(3)] and [(PtMe3)(3){mu-I,mu-S(CH2)(2)NHEt2}(2)]I. H-1 NMR data in solution for the former complex and the X-ray structure of the latter show that both are structurally related to the initial [PtMe3I](4) cubane. The replacement of iodine by 2-dimethylaminoethanethiol has led to [Pt(II){Pt(IV)Me-3(SCH2CH2NMe2)(2)}(2)], as the only product. The X-ray structure of this complex can be described as consisting of two Pt(IV)Me-3(SCH2CH2NMe2)(2) octahedra linked to a naked Pt(II) atom by means of the thiolate sulfur atoms. Consequently, a total substitution of iodine in [PtMe3I](4) together with the reduction of Pt(IV) to Pt(II) have taken place. The reaction of [PtMe3I](4) with the cyclic 3-aminoalkanethiol HSCH(CH2CH2)(2)NMe and with the acyclic 3-aminoalkanethiol, HS(CH2)(3)NMe2, afforded the complexes Na[(PtMe3)(2){mu-SCH(CH2CH2),NMe}(3)], [(PtMe3)(2){mu-SCH(CH2CH2)(2)NHMe}(3)]I-2, and [(PtMe3)(2){mu-S(CH2)(3)NHMe2}(3)]X-2 (X = I or BPh4). They all consist of face-shared bioctahedral diplatinum(IV) units of general formula [Me3Pt(mu-SR)(3)PtM3](z), in which the 3-aminothiolates function as bridging ligands through their sulfur atoms. Overall, in the case of 3-aminothiols there is a total replacement of iodine, which is accompanied by the disruption of the initial cubane structure. (C) 2000 Elsevier Science S.A.
