Diphenyl diselenide (PhSeSePh) was effective as a pre-catalyst for the vicinal dichlorination of α,β-unsaturated phosphonates with sulfuryl chloride. The reaction conditions were mild and the desired products were formed in up to 93% yield and moderate diastereoselectivity (10 : 1). The important diphenylselenium dichloride intermediate was obtained and characterized by X-ray crystallography.
二苯二硒化物(PhSeSePh)作为α,β-不饱和膦酸酯与硫酰氯的邻位二氯氯化反应的有效前催化剂。反应条件温和,以高达93%的产率和中等的非对映选择性(10∶1)形成所需产物。获得了重要的二苯基二氯化硒中间体,并通过X射线晶体学表征。
