Synergistic Effects of ppm Levels of Palladium on Natural Clinochlore for Reduction of Nitroarenes

Abstract

Augmenting the modified naturally occurring clay clinochlore with ppm amounts of palladium leads to a new and very effective reagent for the reduction of numerous aromatic nitro species. When palladium nanoparticles are supported on pyridyltriazole‐modified clinochlore, iron within clinochlore acts synergistically with palladium to catalyze the reduction of a wide variety of nitroarenes at room temperature in aqueous media. Based on E‐factor calculations, the catalyst system is found to be in line with green chemistry standards and can be recycled up to five times.
