Abstract

Nanoparticulate intermetallic compound Ni₃Ga supported on SiO₂ has emerged as a highly efficient catalyst for the hydrosilylation of carbonyls, such as aldehydes and ketones, at room temperature. Formation of electron-enriched Ni via alloying with Ga is the key to the catalytic performance.
