S,C- and S,S-coupling via dithiolate transfer reactions from tin to nickel complexes

Abstract

Dithiolate tin(IV) complexes [SnMe2(SS)] (SS = 4,5-dimercapto-1,3-dithiol-2-thione, dmit; 1,2-benzene dithiolate, bdt; and 3,4-toluene dithiolate, tdt) are used as transmetallating agents in the reaction with nickel derivatives [NiBrR′(PR3)2] (R′ = mesitylene (Mes) and 2,4,6-trisisopropylphenyl (Trip), and PR3 = PPh3 and PPh2Me). The reaction results in the isolation of different complexes with a great variety of stoichiometries, including mono-, di- and trinuclear nickel complexes with the general formulae: [Ni(SS)(PR3)]2, [Ni(Mes)(SS-Mes)(PR3)], [Ni(SS-Mes)2] and [Ni3(bdt)3(PPh2Me)2], and the organic compounds {dmit(Mes)}2, {dmit(Trip)}2, {dbt(Mes)2} and {tbt(Mes)2} as a consequence of S,C- and S,S-coupling processes. In the case of [Ni(Mes)(dmitMes)(PPh2Me)], {dmit(Trip)}2, [Ni3(bdt)3(PPh2Me)2] and [Ni(bdtMes)2] the X-ray analyses are also presented to confirm the proposed structures.
