A-3 Recyclable heterogeneous Gold catalyst supported on thermo-responsible polymer and method for preparing propargylamines via three component A-3 coupling reaction using the catalyst

摘要

The present invention relates to a gold-supported catalyst characterized in that gold (Au (III)) is supported on a polymer support composed of N-isopropylacrylamide and 4-vinylpyridine copolymer having thermosensitive properties and an aldehyde , A method for producing a propargylamine compound through an A-3 bonding reaction between an amine and an alkyne compound, has a high reaction yield, is reusable, and maintains excellent reactivity even using a reusable catalyst It is economical and environmentally friendly.
