Abstract

The reaction of [(n-C4H9)4N][ReOBr4(OPPh 3)] with bis(2-mercaptoethyl) sulfide produces [ReOBr{η3-(SCH2CH2)2S}] (1), which can be reacted in turn to replace the labile bromine atom with various monodentate thiolate ligands. The reactions of [ReOBr{η3-(SCH2CH2)2S}] (1) with (C6H4X-4-CH2S) where X = Br, Cl, F and OMe in alcohol treated with triethylamine has led to the isolation of a series of rhenium complexes of the type [ReO{(SCH2CH2)2S}(C6H 4X-4-CH2S)]. The reaction of [ReOCl3(DMS) (OPPh3)] with 2-mercaptoethyl sulfide and base results in the isolation of [ReO{η3-(SCH2CH2)2S}(η 1-SCH2CH2SCH2CH2SH)] (6) while the reaction of 1 with dithioerythritol and triethylamine results in the formation of [ReO{η3-(SCH2CH2)2S}{η 1-SCH2CH(OH)CH(OH)CH2SH}] (7), unusual examples of '3 + 1' coordination chemistry with a pendant thiol arm. The X-ray structures of [ReO{η3-(SCH2CH2)2S}(C 6H4X-4-CH2S)] (X = Br (2), Cl (3), F (4), and OMe (5)), [ReO(η3-(SCH2(CH2)2S}{η 1-SCH2CH2SCH2CH2SH)] (6) and [ReO{η3-(SCH2CH2)2S}{η 1-SCH2CH(OH)CH2CH(OH)CH2SH}] (7) have been determined.
