Abstract

Reaction of [{(RhCp*)₂(μ-CH₂)₂} ₂(μ₄-S₄)]²⁺ (Cp*=η⁵-C₅Me₅) (1) containing a rectangular S₄ ligand with the reducing agent of NaBH₄ affords [(RhCp*)₂(μ-CH₂)₂(μ-S₂)] (2) confirmed by FAB mass and ¹H NMR spectra. This disulfide complex is so air-sensitive that the S₂ ligand is easily oxygenated by oxygen to give an SSO ligand in [(RhCp*)₂(μ-CH₂)₂(μ-SSO)] (3) whose structure is determined by X-ray analysis.
