Title:
METHOD FOR PREPARING VILSMEIER REAGENT
Document Type and Number:
WIPO Patent Application WO/2020/050368
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a method for preparing a Vilsmeier reagent, that can be carried out safely, easily, and at a low cost; and a method for producing an aromatic aldehyde or an aromatic ketone, a carboxylic halide, and a formic ester. A method for preparing a Vilsmeier reagent according to the present invention is characterized by comprising: a step for degrading C1-4 halogenated hydrocarbon by irradiating with light, in the presence of an enzyme, a composition that comprises a C1-4 halogenated hydrocarbon having at least one halogen group selected from the group consisting of chlorine, bromine and iodine; and a step for reacting a degraded product of the C1-4 halogenated hydrocarbon with a specific amide compound.
