METAL-CATALYZED SYNTHESIS OF CARBOXYLIC ESTERS UTILIZING (E)-PHENYL 2-PYRIDYL KETONE O-ACYLOXIMES (PPAO)

Article abstract of DOI:10.1246/cl.1986.871

(E)-Phenyl 2-pyridyl ketone O-acyloximes (PPAO) could be highly activated by metal ions such as Fe(3+), Cu(2+), and Zn(2+), and the most effective catalyst for the synthesis of carboxylic esters was found to be Zn(2+).Furthermore, sterically hindered carboxylic esters were easily obtained utilizing PPAOs and alcoholates in high yields.
