Résumé

We report that SeO ₂ catalyzes the facile oxy-functionalization of (CO) ₅Re(I)-Me ₄- with IO ₄- to generate methanol. Mechanistic studies and DFT calculations reveal that catalysis involves methyl group transfer from Re to the electrophilic Se center followed by oxidation and subsequent reductive functionalization of the resulting CH3Se(VI) species. Furthermore, (CO) ₃Re(I)(Bpy)-R (R = ethyl, n-propyl, and aryl) complexes show analogous transfer to SeO ₂ to generate the primary alcohols. This represents a new strategy for the oxy-functionalization of M-R4- polarized bonds.
