Abstract
Abstract Borohydride reduction of halopentacarbonylrhenium(I) affords the corresponding formyl complex I , e.g., BrRe(CO) 4 CHO − , which differs from that of many other formylmetals in that its stability is unaffected by tin hydrides. This unusual behavior is attributed to the facile loss of the halide from I to afford the coordinatively unsaturated formyl species Re(CO) 4 CHO which can either rearrange to the hydride complex HRe(CO) 5 or undergo oxidative addition of tin hydride. The behavior toward ligands such as phosphines, carbon monoxide and methyl isocyanide is also described. Although the tin hydride adduct could not be isolated it afforded upon water workup a dirhenium μ-oxodistannylene product, the novel structure of which is established by X-ray crystallography. The pathways for the decomposition of formylrhenium species are discussed.
