摘 要：Our present study unveils a new and efficient N-heterocyclic carbene(NHC)-boryl radical-catalyzed cycloisomerization of N-(2-ethynylaryl)*** catalytic process is triggered by the addition of an NHC-boryl radical to the alkynyl moiety,followed by a radical cascade comprising of an intramolecular cyclization,successive 1,5-and 1,2-aryl migrations,and the reorganization of a C–C triple bond.
