Published: October 2018

A Cu(i)-catalyzed aminoborylation reaction of styrenes is reported. In this transformation, diazo compounds are used as the electrophilic amination agent. The in situ generated benzylcopper species is trapped by the electrophilic nitrogen terminus of the diazo substrate to afford borylated hydrazones in a regioselective manner.
