Isolation and X-ray Structure of an Intermediate in the Reaction of (μ-S)₂Fe₂(CO)₆ with Thiolates: The [(μ-S)(μ-S₂-t-Bu)Fe₂(CO)₆]⁻ Ion
Reaction of (μ-S2)Fe2(CO)6 (1) with 1 equiv of thiolate RS- (R = Ph, PhCH2, i-Pr) results in formation of the [Fe4S4(CO)12]2- ion (2) containing two [(μ-S)2Fe2(CO)6]- units linked by a disulfide bond. Use of t-BuS- results instead in a new green mixed disulfide, the [(μ-S)(μ-S2-t-Bu)Fe2(CO)6]- ion (3), the structure of which has been determined as the Ph4As+ salt. These results suggest that similar mixed disulfides are intermediates in the reaction of thiolates with 1 to produce 2. © 1989 American Chemical Society.
