摘要：

A mild strategy for the synthesis of boron‐handled pyrazoles through photocatalytic cascade radical cyclization of LBRs (Lewis base‐boryl radicals) with vinyldiazo reagents is described here. The reaction starts with the addition of LBRs at diazo site, followed by intramolecular radical cyclization to access a wide range of important boron‐handled pyrazoles in good to excellent yields. Control experiments, together with detailed mechanism studies well explain the observed reactivity. Abstract Vinyldiazo compounds are one of the most importan...
