1-(trimethy1silyl)cyclopropanesulfonyl chloride (3) in the presence of 1 -(N,N-diethylamino) 1 -propyne affords 4-(N,N-diethylamino)-3-methyl-2-thiaspiro( 3.21 hex-3-ene 2,2-dioxide (19) in 56% yield by way of IC. Treatment of cyclopropanesulfinyl chloride (7) with triethylamine gives triethylamine hydrochloride in 90% yield along with S- 1 -chlorocyclopropyl cyclopropanethiosulfonate (18), S-cyclopropyl
