Pd(II)-Catalyzed Olefination of sp3 C−H Bonds

Abstract
The first Pd(II)-catalyzed sp3 C−H olefination reaction has been developed using N-arylamide directing groups. Following olefination, the resulting intermediates were found to undergo rapid 1,4-addition to give the corresponding γ-lactams. Notably, this method was effective with substrates containing α-hydrogen atoms and could be applied to effect methylene C−H olefination of cyclopropane substrates.
