Palladium-Catalyzed Alkylation of sp~2 and sp~3 C-H Bonds with Methylboroxine and Alkylboronic Acids:Two Distinct C-H Activation Pathways

摘要

The development of C-H activation/C-C bond forming reactions catalyzed by transition metals has received much attention recently.A wide range of efficient Ru- and Rh-catalyzed alkyla-tions and arylations of aryl C-H bonds have been achieved with olefins or aryl organometallic reagents.Pd-catalyzed alkenylation of aryl C-H bonds via Pd~(II)/Pd~0 catalysis has been reported.
