A palladium-catalyzed ortho-acylation of N-benzyltriflamides with aldehydes via direct sp2 CH bondactivation is described. Benzylamines with a triflamide directing group in the presence of palladium acetate, acetic acid, and tert-butyl hydroperoxide as an oxidant can be effectively coupled with aryl and alkyl aldehydes to provide ortho-acyl-N-benzyltriflamides with a high regioselectivity.

A palladium-catalyzed ortho-acylation of N-benzyltriflamides from the alcohol oxidation level via C–H bondactivation is described. These transformations have been applied to a wide range of substrates, and typically proceed with excellent levels of chemoselectivity and with high functional group tolerance.
