Palladium-catalyzed primary and secondary sp3 C–H bond arylation is reported. The method using diarylhyperiodonium salts as arylation reagents shows good functional group tolerance and proceeds under mild reaction conditions. The KIE experiments show that the C–H bond activation is the rate-determining step.

ortho-sulfinylaniline auxiliaries for palladium-catalyzed β–C-H arylation of alkyl carboxamides. Together, these auxiliaries offer a means to effect efficient β-methyl and methylene C–H bond arylation with sterically hindered aryl iodides. ortho-Methylsulfinylaniline (MSOA) enables efficient β-methyl C–H arylation of propanamide substrates with aryl iodides bearing various ortho-substituents including alkyl
