Photoinduced Intermolecular Radical Hydroalkylation of Olefins via Ligated Boryl Radicals-Mediated Halogen Atom Transfer

“…In view of the above, we wondered if tuning the L B of LBR could be an effective strategy to obtain a smooth radical chain to achieve intermolecular RRH without the need for superstoichiometric agents or high temperatures. Herein, we describe the use of NHC-ligated boranes 20 for the successful implementation of this hypothesis ( Scheme 1 C) for C(sp 3 )–C(sp 3 ) and C(sp 3 )–C(sp 2 ) bond formation.…”
