摘要：C-Hborylation is one of the powerful C-H bond functionalizationreactions. In this context, a metal-free C-H borylation ofbenzophenones using hydrazone as the traceless directing group hasbeen reported. The dibromoboron intermediates can be obtained in excellentyields, and the corresponding arylboronic esters are generated inmoderate to excellent yields. Furthermore, the borylated compoundscan be transformed in a one-pot method, avoiding the loss of overallyield caused by the separation of the arylboronic esters.
