Procedure

When a mixture of 10 ml of di-t-butyl sulfide and 10 ml of dimethyl sulfoxide was heated at 300° F. (149° C.) for about 40 minutes in the presence of catalytic amounts of zinc chloride and hydrochloric acid, gas-liquid chromatography indicated an 85 percent yield of di-t-butyl disulfide. The identity of the product was confirmed by mass spectrometry and infrared spectroscopy.
