Baeyer-Villiger reaction can take control of the stereochemical structure of the product. It is significant in organic synthesis for the conversion of functional groups and ring expansion.The oxide product of Baeyer-Villiger reaction can be widely used in the synthesis of many natural products and pharmaceutical intermediates, as well as some polymer material monomer. With the further research on Baeyer-Villiger reaction, the types of catalysts are increasing continuously, including homogeneous catalysts, heterogeneous catalysts, biocatalysts. Homogeneous catalyst often brings excellent conversion rate and good selectivity, but has lower recycling rate than the heterogeneous catalyst. And the environmentally-friendly biocatalysts are still the focus of the study. In this review, we provide an overview of the latest achievements in Baeyer-Villiger reaction from the aspects of homogeneous catalysis, heterogeneous catalysis and biocatalysis, especially with an emphasis on the clarification of the relationship between catalysts and substrates in different catalyst systems. The mechanisms of the reaction are summarized in detail in the review. And the future advance of Baeyer-Villiger reaction is prospected. Contents
