A direct route: The N‐transacylation of secondaryamides to their perfluorinated analogues with the possibility of subsequent conversion into a normal amide is reported (see scheme). This reaction occurs in the presence of a variety of functional groups that are labile to the hydrolysis conditions required by classical N‐transacylation.

The simple addition of mild bases (Et3N or DIPEA) allows a high yielding N-transacylation of secondaryamides, performed by perfluorinatedanhydrides, in molecules that are very sensitive to acids.
