The metal‐stabilized thiyl radical complex [Ru(SP) 3 ] + , [Ru‐ 1 ] + , {SP = 2‐(diphenylphosphanyl)benzenethiolate} adds 1‐octyne across the cis ‐sulfur sites to yield the S ‐alkylated dithiolene product [Ru‐ 1· octyne] + . The product complex exists as a pair of inseparable geometric isomers, which were characterized by X‐ray crystallography, 31 P NMR spectroscopy, and cyclic voltammetry. By using electrochemical methods, the rate constant for 1‐octyne addition was determined as 8.7 × 10 3 M –1 s –1 .
