长碳链对称二酮化合物是合成具有旋光活性的天然产物(如昆虫性信息素)和具有生理活性的大环烯烃等的重要中间体[1,2].而长碳链对称二酮的合成工作只是在近几年引起人们的兴趣[3].本文报道以癸二酸为原料经反应合成1,10——二苯基——1,10——癸二酮.其反应如下: Long carbon chain symmetric diketone compounds are important intermediates for synthesis of optically active natural products (such as insect pheromones) and macrocyclic olefins with physiological activity [1,2]. The synthesis of long carbon chain symmetric diketones The work only aroused people’s interest in recent years [3] .This paper reports the synthesis of 1,10-diphenyl-1,10-decanedione by using sebacic acid as raw material.The reaction is as follows:
