Reaction Steps

To a stirred solution of dimethyl sulphide (0.20 mmol), rhodium (II) acetate (0.01 mmol) and p-chlorobenzaldehyde (1 mmol) in dichloromethane (4 ml) was added a solution of phenyldiazomethane (1 mmol in 6 ml of tert-butylmethyl ether) at room temperature over a period of 24 hours. After addition was completed the solvent was removed in vacuo and the residue was chromatographed over silica to provide the title oxirane in 76% yield.
