Abstract

Abstract The combination of AgNO 3 with NaH results in Ag nanoparticles that can selectively perform alcohol aminations under mild reaction conditions (110 C). NaH not only serves as a reducing agent for the Ag salt, but also activates the alcohol for dehydrogenation to the corresponding ketone/aldehyde. The stability of the particles can be improved by immobilizing them onto mixed Al 2 O 3–Ga 2 O 3 supports; the combination of Ga and Al ...
