实验步骤: To a mixture of 1.08 g. of benzylalcohol, 1.16 g. of caproic acid, 2.20 g. of 2,2'-dipyridyl disulfide and 50 ml. of methylene chloride is added dropwise a solution of 2.62 g. of triphenyl phosphine in 20 ml. of methylene chloride while stirring at room temperature. After completion of the addition, the mixture is stirred at room temperature for an additional 3 hours. The reaction mixture is treated with the same procedure as in Example 1 (1) to give 1.9 g. of the desired product boiling at 75°C/0.2 mmHg. To a mixture of 1.08 g After completion of the addition to give 1.9 g
