One-Pot Synthesis of Au@SiO
2 Catalysts: A Click Chemistry Approach.
ACS Comb. Sci. 2014;
16: 513-517
Key words
triazoles - hydroamination - gold nanoparticles - heterogeneous catalysis
Significance
The porous Au@SiO2 catalyst was prepared from a gold precursor and a TEOS solution in the presence of
cinchonidine-based triazole amphiphiles. The hydroamination of alkynes was carried
out with Au@SiO2 to give the corresponding imine products 1a–n in up to 99% conversion.
Comment
The turnover number of Au@SiO2 was 1604 for the formation of 1b. The catalyst was characterized by cryo-TEM, XPS, UV/Vis, zeta potential, and ICP-OES
analyses.
