New organoplatinum-rhenium heterobimetallic complexes (organic ligand = Me (1), Et (2), CH2Ph (3), Ph (4)) with sulfur ligands have been prepared and characterized by IR, IH and 13c{1n} NMR, elemental analysis, and chemical reactions. Complex 1 was thermally more stable than related PtMeCi(cod) (5)
Chiral racemic rhenium thiolate complexes [CpRe-SCH 2 CH 2 NHAc (8), SCH 2 CH 2 C(O)OH (9). A milder synthesis using hydrated sodium carbonate as a base (NO)(PPh 3 )(SR)] were obtained under either acidic or basic conditions. Thus, when [CpRe(NO)(PPh 3 )(CH 3 )] (1) was provided 8 and compounds with
