Rhodium‐Catalyzed Benzylic Addition Reactions of Alkylarenes to Michael Acceptors

-coordination, dramatically facilitating deprotonation of the unactivated benzylic C-H bond and addition of the resulting carbanion to the α,β-unsaturated double bond in the absence of bases. Notably, this byproduct-free method provides an access to all-carbon quaternary centers through the development of ligands.
