- W2091658846 abstract "Abstract Reaction of the tetranuclear complex [Me 3 PtI] 4 with the ligand o -Ph 2 P(E)C 6 H 4 SMe (E=S, Se) in a 1:4 molar ratio yields the mononuclear neutral complexes [Me 3 PtI{η 2 -MeSC 6 H 4 P(E)Ph 2 -S,S}] (E=S( 1 ), Se( 2 )). Iodide abstraction from these compounds with AgPF 6 in the presence of a ligand L (PPh 3 , py) leads to cationic complexes of the type [Me 3 Pt(η 2 -MeSC 6 H 4 P(E)Ph 2 -E,S)L]PF 6 [E=S, L=PPh 3 ( 3 ), Py ( 4 ); E=Se, L=Py ( 5 )]. However, using complex 2 and the ligand PPh 3 under identical conditions induces a reductive elimination reaction affording the Pt(II) complex [MePt(η 2 -MeSC 6 H 4 PPh 2 -P,S)(PPh 3 )]PF 6 ( 6 ). Reactions of complexes 3 and 4 with NaI reveal a nucleophilic attack of the iodide to one of the methyl groups bonded to the platinum center generating a series of subsequent side reactions. Complex [Me 3 Pt{η 2 -MeSC 6 H 4 P(S)Ph 2 -S,S}(py)]PF 6 ·CH 2 Cl 2 ( 4 ) was additionally characterised by X-ray diffraction. The platinum atom exhibits a distorted octahedral coordination, bonded to three methyl carbon atoms in a facial arrangement; a bidentate chelate S,S′-bonded ligand and a nitrogen atom of the pyridine ligand complete the metal coordination sphere." @default.
