| Abstract
| - The reaction of Cp‘ReCl4 (Cp‘ = EtMe4C5) with 2−3 equiv of (Me3Si)2S in air proceeds to form Cp‘ReS3Cl2, 2. Complex 2 reacts with H2 under mild conditions to generate H2S, HCl, and Cp‘2Re2S4, 3. Further reaction of 3 with benzyl bromide forms the alkylated dication [(Cp‘Re)2(μ-S2)(μ-SCH2Ph)2]2+, 4, characterized by an X-ray diffraction study.
- The reaction of Cp‘ReCl4 (Cp‘ = EtMe4C5) with 2−3 equiv of bis(trimethylsilyl)sulfide inchloroform in the presence of an oxidant results in the formation of Cp‘Re(η2-S3)Cl2, 2.Complex 2 has been characterized by spectroscopic methods, and its structure has beenconfirmed by an X-ray diffraction study. Complex 2 reacts with hydrogen under mildconditions to form H2S, HCl, and a rhenium product tentatively identified as (Cp‘Re)2S4, 3.Complex 3 reacted with benzyl bromide to form [(Cp‘Re)2(μ-S2)(μ-SCH2Ph)2]Br2, 4, whichhas been completely characterized by spectroscopic studies and an X-ray crystal structure.The structures and reactions of the Cp‘Re derivatives with sulfur ligands are compared tothose of the related tetrasulfur-bridged CpMo derivatives.
