Abstract

Reactions of electrophiles with [Rh₁₇S₂(CO)₃₂]^3-, produce the adducts [Rh₁₇S₂(CO)₃₂E]^2-, E = Au(PPh₃), Au(PPh₂Me), Ag, Rh(COD), Pt(COD)Cl, and Pd(COD)Cl, characterized by spectroscopic methods. The ¹³C NMR spectrum of [Rh₁₇S₂(CO)₃₂Au(PPh₃)]^2- suggests that addition of the electrophile occurs at a Rh-Rh edge between the basal and internal Rh₄ planes. Cyclic voltammo-grams for [Rh₁₇S₂(CO)₃₂]^3- and [Rh, ₇S₂(CO)₃₂AuL]^2- show several irreversible oxidation processes but two 1-electron reductions, the first of which is nearly reversible.
