Thermal and Photochemical Reactions of Methylrhenium Diperoxide: Formation of Methyl Hydroperoxide in Acetonitrile

Compared to the system in aqueous solution, the equilibration reactions in acetonitrile between MTO and the methylrhenium peroxides CH3ReO2(η2-O2) (A) and CH3ReO(η2-O2)2(H2O) (B) are slower but more favored thermodynamically. In CH3CN, small concentrations of water facilitate the formation of A (especially) and B. These species decompose to methyl hydroperoxide and perrhenic acid in CD3CN, rather than to methanol and perrhenic acid as in aqueous solution. The proposed mechanism involves the intramolecular migration of the methyl group to a peroxo oxygen, followed by hydrolysis, and it is facilitated by photolysis. The potential use of B as photocatalyst does not seem promising, however.

Methyl transfer from rhenium to coordinated thiolate groups

Methylation of a thiolate group, which has only been observed in vitamin B12 and its mimics, has been accomplished with [MeReO3] and [MeReO(edt)PPh3] (edt = 1,2-ethanedithiolato; see scheme). The proposed mechanism involves the formation of [MeReVIIO(edt)2] through two stepwise condensation reactions; nucleophilic attack of a thiolate ligand on the methyl group leads to the product.
