FE NANOPARTICLES WITH PPM CONTENTS OF PD, CU AND/OR NI, REACTIONS IN WATER CATALYZED BY THEM
-
Paragraph 0084; 0100, (2017/07/14)
The present application discloses a nanoparticle composition prepared from a mixture comprising: a) a transition metal salt; b) an iron salt; and c) a reducing agent; and methods for the use of such compositions, including the reduction of an organic compound comprising a nitro group to form an organic compound comprising an amine group, the Cu-catalyzed cyclization of an azide and an alkyne (click chemistry) and cross coupling reactions, notably Suzuki-Miyaura reactions. The transition metal salts are in particular Pd, Cu and Ni salts, the content of these metals being typically in the ppm range based on the major constituent Fe in the final products.

As a result of a unique synergy between ligand-free Fe/ppm Pd nanoparticles and PEG-containing designer surfactants, a facile and selective reduction of nitro-containing aromatics and heteroaromatics can be effected in water at room temperature in the presence of NaBH4. This new nanotechnology involves low catalyst loadings, is highly chemoselective, and tolerates a wide variety of functional groups. The process, which includes recycling of the entire aqueous medium, offers a general, environmentally responsible, and notably safe approach to highly valued reductions of nitro-containing compounds.
