An efficient, green and reliable method for the direct reductivea mination of aldehydes was developed using an environmentally benign bentonitegold nanohybridc atalyst. Use of this heterogeneous catalyst affords av arietyo fs econdary amines in excellenty ield under ambient reactionc onditions in the presenceofp henyldimethylsilane as mild hydride donor. Thec atalyst is recyclable,s elective and is well applicablef or the gram-scale preparation of secondary amines.

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.
