摘要：

Reaction of [{(RhCp*)(2)(mu-CH2)(2)}(2)(mu(4)-S-4)](2+) (Cp*=eta(5)- C(5)Me(5)) (1) containing a rectangular S-4 ligand with the reducing agent of NaBH4 affords [(RhCp*)(2)(mu-CH2)(2)(mu-S-2)] (2) confirmed by FAB mass and H-1 NMR spectra. This disulfide complex is so air-sensitive that the S-2 ligand is easily oxygenated by oxygen to give an SSO ligand in [(RhCp*)(2)(mu-CH2)(2)(mu-SSO)] (3) whose structure is determined by X-ray analysis.
