Title:
METHOD FOR PRODUCING ORGANIC COMPOUND
Document Type and Number:
WIPO Patent Application WO/2020/162630
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide a method for producing an organic compound, etc. Said purpose is solved by a method for producing a compound represented by formula (1). [In the formula, X represents -O-, an imino group which may have a substituent, or -S-, R1 represents a hydrogen atom or a hydrocarbyl group which may have at least one substituent, and R2 represents a hydrogen atom or a monovalent organic group. Alternatively, R1 and R2 may join together with X and one carbon atom which are respectively adjacent thereto to form a heterocycle which may have at least one substituent, R3 represents a hydrogen atom or a monovalent organic group, and R4 is -CF2CH3 or -CH2CHF2.] The production method includes a step A for reacting a compound represented by formula (2) (signs in the formula have the same meaning as above) with vinylidene fluoride under light irradiation.
