Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A process of conducting a Baeyer-Villiger oxidation which comprises contacting a ketone and an oxidant in the presence of a Sn-DZ-1 catalyst to thereby oxidize the ketone to an ester, wherein the Sn-DZ-1 catalyst is prepared by a method comprising delaminating ERB-1 layered borosilicate zeolite precursor by contacting the ERB-1 with a solution comprising a metal salt. 2. The process of claim 1 , wherein the ketone comprises a cyclic ketone such that its Baeyer-Villiger-oxidation product is a lactone. 3. The process of claim 1 , wherein the ketone comprises 2-adamantanone. 4. The process of claim 1 , wherein the ketone comprises 5-hydroxyl-2-adamantanone. 5. The process of claim 1 , wherein the ketone comprises 5-bromo-2-adamantanone. 6. The process of claim 1 , wherein the oxidant comprises a peroxy acid. 7. The process of claim 1 , wherein the oxidant comprises hydrogen peroxide. 8. The process of claim 1 , wherein the oxidant comprises an organic hydroperoxide. 9. The process of claim 1 , wherein a solvent is used for the reaction which comprises dioxane. 10. The process of claim 1 , wherein the metal salt comprises an Al, Zn, or Mn cation. 11. The process of claim 1 , wherein the metal salt comprises a Ga cation. 12. The process of claim 1 , wherein the Sn-DZ-1 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. 13. The process of claim 12 , wherein the lattice framework comprises large pore 12 member ring or larger openings at the external surface of the framework, and 10 member ring or smaller openings beneath the external surface large pore openings. 14. The process of claim 12 , wherein the external surface of the framework comprises 12 member ring openings with 10 member ring openings beneath the external surface 12 member ring openings.
