enzene. Acid fluorides were converted into acylphosphine sulfides and thioesters using diphosphine disulfides and disulfides/triphenylphosphine, respectively. Aryl esters were obtained fromacid fluorides and phenols in the presence of triphenylsilane. Aryl esters, acylphosphine sulfides, and thioesters were also interconverted in the presence of rhodium complexes. These rhodium-catalyzed acyl transfer

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
