Yield:544-40-1 95%

Reaction Conditions:

with potassium ethyl xanthogenate at 120; for 12 h;Inert atmosphere;

Steps:

10 Example 10 Preparation of di-n-butyl sulfide

Under a nitrogen atmosphere,Bromobutane (136 mg, 1 mmol),Ethyl xanthate (80 mg, 0.5 mmol),N, N-dicarboximide (2 ml) was added to the dried reaction tube,Suspended in oil bath at 120 ° C for 12 h. After the reaction system was cooled,15 ml of water was added,The aqueous phase was extracted three times with 30 ml of ethyl acetate,The organic phases were combined,The solvent was evaporated under reduced pressure,Column chromatography gave di-n-butyl sulfide as a colorless oily liquid.(71 mg, yield 95%).
