Procedure

460 mg (0.5 mmol) of tris-triphenylphosphinerhodium chloride (=1 mol-%, with respect to the reaction component) are added to a 100 ml autoclave. After purging with nitrogen, an air-free solution of 15.7 g (0.05 mol) of 4-chlorophenyl-ethenyl 1-phenylmercapto-cyclopropyl ketone in 40 ml of toluene is added and the mixture is heated to 50° C. under a hydrogen pressure of 30 bar. The hydrogen pressure is held between 40 and 50 bar until gas uptake has ended. The mixture is then reacted for a further hour. For working up, the solvent is stripped off under reduced pressure and the residue remaining is purified on silica gel using dichloromethane as eluant. 14.2 g (90% of theory) of 4-chlorophenylethyl 1-phenylmercaptocyclopropyl ketone are obtained in the form of an oily product.
