Abstract
The reaction of Cp ' ReCl4 (Cp ' = EtMe4C5) with 2-3 equiv of bis(trimethyl silyl)sulfide in chloroform in the presence of an oxidant results in the fo rmation of Cp ' Re(eta (2)-S-3)Cl-2, 2. Complex 2 has been characterized by spectroscopic methods, and its structure has been confirmed by an X-ray di ffraction study. Complex 2 reacts with hydrogen under mild conditions to fo rm H2S, HCl, and a rhenium product tentatively identified as (Cp ' Re)(2)S- 4, 3. Complex 3 reacted with benzyl bromide to form [(Cp ' Re)(2)(mu -S-2)( mu -SCH2Ph)(2)]Br-2, 4, which has been completely characterized by spectros copic studies and an X-ray crystal structure. The structures and reactions of the Cp ' Re derivatives with sulfur ligands are compared to those of the related tetrasulfur-bridged CpMo derivatives.
