Title:
3, 3-DIFLUOROALLYLIC ONIUM SALT COMPOUND AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/030279
Kind Code:
A1
Abstract:
Provided are a 3, 3-difluoroallylic onium salt as represented by formula (C), and a preparation method of the substance. Cheap industrial raw materials are used to prepare the important fluorine-containing reagent, which can be used as an α,α-gem-difluoroallylation reagent. The present invention provides a more universal and cheap new method for α,α-gem-difluoroallylation, and is high in efficiency and good in application prospects.
