| Popis: | Reaction of Cp*2Mo2O5 with HSCH2CH2COOH in acidic (by CF3COOH) 50:50 MeOH-H2O solvent at room temperature yields compound Cp*2Mo2(μ-O)(μ-SCH2CH2CO2)2, a dinuclear diamagnetic MoIV compound with a two-leg-sharing bis(four-legged piano stool) structure and a Mo-Mo distance of 2.6833(6) A. A reaction monitoring by ESI MS shows the formation of an intermediate 18 mass units heavier, interpreted as a dihydroxo analogue. Electrochemistry shows a reversible, pH independent oxidation process and an irreversible, pH-dependent reduction process. Contrary to a recently published analogous reaction with the closely related HSCH2COOH substrate, this process does not lead to C-S bond cleavage. |
