A Bentonite–gold Nanohybrid as a Heterogeneous Green Catalyst for Selective Oxidation of Silanes

Abstract

A highly efficient, environmentally benign and reusable heterogeneous bentonite–gold nanohybrid catalyst was designed and synthesized. This heterogeneous catalyst could efficaciously catalyse the oxidation of organosilanes to silanols. The reaction is 98.7% atom economical and the products were obtained in excellent yield without the formation of disiloxanes as byproducts. The catalyst was also well applicable for the gram scale preparation of silanols
