1-(isopropylsulfanyl)-2-vinylbenzene (25.0 mg, 0.14 mmol), cuprous chloride (16.7 mg, 0.17 mmol) and (1,3-Bis(2,4,6-trimethylphenyl)-2-imidazolidinylidene)dichloro(phenylmethylene)(tricyclohexylphosphine)ruthenium (119 mg, 0.14 mmol) were dissolved in 6 mL dichloromethane in a 10 mL round-bottomed flask under dry nitrogen topped with a reflux condenser. The reaction mixture was refluxed for 4.5 h. The resulting mixture was evaporated to dryness. The crude product was purified by chromatography on silica gel using 7:3 n-hexane and acetone as eluent to give a teal solid (48.0 mg, 55%). Two additional byproducts were separated by chromatography, but only one was fully characterized by NMR analysis: the trans-catalyst isomer green solid (8.1 mg, 9%) and additional green solid (14.2 mg). Both spontaneously converted with time to product 1A according to NMR analysis.
