[ReOCl3(PPh3)2] as a substrate for the synthesis of the rhenium(I) carbonyl complexes [Re(CO)2(OAc)(PPh3)2] and [ReCl(CO)3(PPh3)2]

New preparative methods have been developed for the synthesis of the rhenium(I) carbonyl complexes [Re(CO)2(OAc)(PPh3)2] (1) and [ReCl(CO)3(PPh3)2] (2). Acetic anhydride was decarbonylated during the course of its reaction with [ReOCl3(PPh3)2], resulting in the formation of the rhenium(I) carbonyl complex [Re(CO)2(OAc)(PPh3)2] (1), which was subsequently converted almost quantitatively to [ReCl(CO)3(PPh3)2] (2) via the decarbonylation of its acetate group under acidic conditions.
