Abstract

In recent years, transition-metal-catalyzed inert C-H bond activation has developed rapidly and is a powerful protocol for the construction of new C-C or C-X bonds and the introduction of new functional groups. Our group has also developed a series of R2(O)P-directed Pd-catalyzed C-H functionalizations involving olefination, hydroxylation, acetoxylation, arylation, and acylation through an uncommon seven-membered cyclo-palladium pretransition state. Unlike previously used directing groups, the R2(O)P group acts as a directing group and is also involved in the construction of P,-hetero-ligands.
