A metal-free and hypervalent iodine free conversion of internal alkynes into 1,2-diketo compounds has been described. The efficacy of the present protocol rely on the use of HFIP (1,1,1,3,3,3-Hexafluoro-2-propanol) as reducing agent of alkynes and DMSO as dihydroxylating agent of olefins to acquire the desired chemical transformations. The obtained 1,2-diketones were further transformed into useful
已经描述了内部炔烃的无金属和高价碘的转化为1,2-二酮化合物。本协议的效力取决于使用HFIP(1,1,1,3,3,3-六氟-2-丙醇)作为炔烃的还原剂,而DMSO作为烯烃的二羟基化剂来获得所需的化学转化。将获得的1,2-二酮进一步转化为有用的衍生物。
