Palladium nanoparticles supported on silica diphenylphosphinite as efficient catalyst for C‐O and C‐S arylation of aryl halides

Abstract

Silica diphenylphosphinite (SDPP) can be easily obtained through direct phosphorylation of silica gel. Further reaction of SDPP with Pd(II) produces nano Pd(0)/SDPP. This nano Pd(0) catalyst exhibits excellent reactivity for the C‐O and C‐S arylation of different aryl iodides, bromides and chloride with phenols and thiophenols. This heterogeneous catalyst shows excellent recyclability and can be easily recovered and reused for several runs. Copyright © 2013 John Wiley & Sons, Ltd.
