We devise a new and green route for the multi-gram synthesis of core–shell nanoparticles (NPs) in one step under organic-free and pH-neutral conditions. Simply mixing core and shell metal precursors in the presence of solid metal oxides in water allowed for the facile fabrication of small CeO2-covered Au and Ag nanoparticles dispersed on metal oxides in one step. The CeO2-covered Au nanoparticles acted as a highly efficient and reusable catalyst for a series of chemoselective hydrogenations, while retaining C=C bonds in diverse substrates. Consequently, higher environmental compatibility and more efficient energy savings were achieved across the entire process, including catalyst preparation, reaction, separation, and reuse.

Paragraph 0043; 0044, (2017/03/28)
PROBLEM TO BE SOLVED: To provide a method for producing an unsaturated group-containing halide whereby an unsaturated group-containing halide expected or used as an intermediate in the fields of medicine, agrochemical, resin and the like can be produced by a safe method, easily and at good yields. SOLUTION: The present invention provides a method for producing an unsaturated group-containing halide represented by formula (3) by halogenating an unsaturated group-containing alcohol represented by formula (2), in the presence of an organic base, with a sulfonic acid halide as a halogenating agent [R2 and R3 are H or unsubstituted; n is an integer of 1-6; and an unsaturated bond is a double bond or a triple bond].
