Abstract
|
A novel, efficient, and core/shell nanosphere catalyst (Fe3O4@C-NHCS-Au0) was successfully synthesized with a movable magnetite core encapsulated in a carbon shell. It was modified using APTES (3-aminopropyltriethoxysilane) to convert dithiocarbamate (DTC) functional group in the carbon surface though post-modification with CS2 (carbon disulfide). Au0-nanoparticles were decorated via DTC binder to improve the catalytic activity. It was applied as a high-efficiency nanocatalyst in promoting three-component A3 coupling reaction of alkynes, aldehydes, and amines for the synthesis of propargyl amines under the optimized condition.
