Abstract

Provided is a process of conducting a Baeyer-Villiger oxidation which comprises contacting a ketone and an oxidant in the presence of an Sn-DZ-1 catalyst to thereby oxidize the ketone to an ester. The Sn-DZ-1 catalyst comprises Sn heteroatoms on the external surface of the zeolitic material lattice framework, and B heteroatoms, or silanols created from boron hydrolysis, throughout the remainder of the lattice framework.
