Iodine → Heptadecane

참여 물질

반응 단계

140 mg (1.1 mmol) of N-hydroxypyridine-2-thione in 5 ml of benzene are added dropwise at room temperature under an atmosphere of nitrogen to a solution of 120 mg (1.2 mmol) of phosgene in 5 ml of benzene, and this leads to the instantaneous precipitation of a white solid. 286 mg (1 mmol) of stearic acid and 0.5 ml of pyridine are added in 5 ml of benzene, and the reaction medium is taken to reflux for 4 hours. 3 mmol of tri-n-butylstannane in 5 ml of benzene with 10 mg of AIBN are added to the reaction medium during 10 minutes and refluxing is maintained for 2 and half hours. The reaction is carried out in the presence of tetrachloromethane, iodine and potassium fluoride, as indicated earlier. By filtration on silica (100% pentane), 168 mg of n-heptadecane are obtained. Yield 70%.
