S-Alkylation-induced redox reactions leading to reversible sulfur�sulfur coupling in a pentamethylcyclopentadienyl ruthenium(III) thiolate-thioether system

Abstract

Alkylation of [Cp*RuIII(tpdt)] (2) (Cp* = η5-C5Me5, tpdt = η3-S (CH2CH2S-)2) with MeI orMe3OBF4 resulted in the formation of a trans μ-η1-η1-S2 coupled species, [{Cp*RuII}2{μ-η6-(S(CH2)2S(CH2)2SMe)2}]2+ (3) as the predominant product. With MeI the Show more
