Abstract

This invention has two important disclosures. The first is a method for preparing a highly active silica-supported palladium catalyst. The second is the possibility of applying this method to synthesise different high-value amines using alcohol, nitroarenes and amines. The method is used in the preparation of particles of the present drugs/pharmaceuticals (benzylaniline). This catalyst is useful in a process for producing primary amines from alcohol and amines, which is considered a very difficult process.
