approach for the activation of esters via a radical-mediated process enabled by a copper/Selectfluor system. A variety of para-methoxybenzyl esters derived from bulky carboxylicacids and amino acids can be easily converted into the corresponding acyl fluorides, directly used in the one-pot synthesis of amides and peptides. As a proof of concept, this method was applied to the iterative formation of sterically

A rhodium complex catalyzed the reaction of acidfluorides and tetraethyldiphosphine disulfide giving acylphosphine sulfides. Aromatic acidfluorides with electron donating p-groups reacted smoothly giving the products in high yields. Aliphatic acidfluorides with secondary and tertiary α-carbons were also converted to alkanoylphosphine sulfides, whereas the reaction of a substrate with an α-methylene
