diethyl acetal sulfide 8 with methanesulfenyl bromide at low temperature results in an efficient thiirane ring opening to a halo disulfide 9. The bromine in this halo disulfide is easily substituted by silver acetate, sodiumazide, sodium iodide, and silver nitrate. Treatment of 9 with tetrabutylammonium acetate yields a novel dehydrohalogenation product 12. Silica gel converts bromide 9 into a disulfide-substituted
