Title:
PREPARATION METHOD FOR ACETAMIDE COMPOUND BY MEANS OF GREEN VISIBLE-LIGHT CATALYSIS
Document Type and Number:
WIPO Patent Application WO/2023/040106
Kind Code:
A1
Abstract:
Disclosed in the present invention is a preparation method for an acetamide compound by means of green visible-light catalysis. In the method, LED lamps are used as light sources to provide energy, and economically available aromatic amines and aliphatic amines and commercially available 2,3-butanedione are used as reaction substrates. Compared with the prior art, the method of the present invention has the following advantages: 1) a green, efficient, energy-saving, and environmentally friendly visible-light catalysis reaction mode is used; 2) a reaction system is simple, there is a wide range of substrates, and there is no need to add a metal catalyst and a dehydrating agent; 3) the reaction yield is relatively high; 4) reaction conditions are mild; 5) operations are relatively simple; and 6) raw materials are cheap and easily available.
