Abstract

Efficient and site selective boron-copper addition processes involving acyclic and cyclic disubstituted aryl olefins are promoted with a readily available N-heterocyclic carbene (NHC) complex. In situ protonation of the C-Cu bond in the presence of MeOH leads to efficient catalyst turnover, constituting a net Cu-catalyzed hydroboration process.
