ResumoTreatment of Fe 2 (CO) 9 with sulfur-transfer reagents of the types ImideSSImide and RSSImide where H-imide = phthalimide, succinimide, benzimidazole, morpholine and piperazine, and R CH 2 Ph and CMe 3 leads to cleavage of both the sulfursulfur bond and the sulfurnitrogen bond to give Fe 3 (CO) 9 S 2 in varying yields, some Fe 2 (CO) 6 S 2 plus low yields of the appropriate dimers of the type Fe 2 (CO) 6 (SR)(SR′), where R = R′ = phthal imido, CH 2 Ph, CMe 3 and R = CH 2 Ph, CMe 3 , R′ = phthalimido. The naturally occurring cyclic disulfide D,L-α-lipoic acid, its methyl ester and amide react with Fe 2 (CO) 9 to give Fe 2 (CO) 6 derivatives wherein the sulfursufur bond has been broken.
