实验步骤: 1-Butoxycarbonylsulfenyl chloride, with a boiling point of 83°-90° C. at 13 mm., was prepared in 84.3% yield by a procedure analogous to that described for methoxycarbonylsulfenyl chloride in Example I by reacting equimolar quantities of 1-butanol and chlorocarbonylsulfenyl chloride. To a stirred solution of 8.4 grams (0.05 mole) of 1-butoxycarbonylsulfenyl chloride and 25 milliliters of hexane was added dropwise with stirring and under nitrogen at 0° C., 4.4 grams (0.025 mole) of 1,8-octanedithiol dissolved in 25 milliliters of hexane. After allowing the solution to warm to room temperature, the solution was concentrated under reduced pressure to give 10.9 grams (98.2%) of 1,8-bis(1-butoxycarbonyldithio)-octane as a pale yellow liquid. , was prepared in 84.3% yield by a procedure analogous to to warm to room temperature the solution was concentrated under reduced pressure
