Abstract
A method for processing of hydrogen for the reductive acylation of nitro, azido and cyano arenes is disclosed. More particularly, improved process for the preparation of amides and anilides using C3-C7 carboxylic acids as proton source/acylating agents employing Fe3+-montmorillonite as a catalyst is disclosed.
Claims25
A method for the processing of hydrogen used in the reductive acylation of nitro, azido, and cyano arenes comprising reacting C3-C7 carboxylic acid as an acylating agent/proton source and iodide as electron source using metal exchanged montmorillonite as a catalyst at a temperature in the range of 116-200° C., recovering the catalyst by filtration for reuse and recovering the acylated product.
