Cyanosilylation of Aldehydes by high sulfonated graphene oxide nanosheets

In this research graphene nanosheets sulfonated and used as hetrogeneous nanocatalysts for cyanosilylation of aldehydes in mild condition. the product were obtained in high yields (up to 99%) and short reaction times (5-20 minites) that charactrized by gas chromatography (GC).The result established by fourrier transform infrared spectroscopy (FT-IR).the catalyst charactrized by X-ray diffraction spectroscopy (XRD) and Transmission electron microscopy (TEM). In addition non-toxicity of catalyst and was reused several times without any appreciable loss of its catalytic activity are environmentally benign and econamical method for synthesis of cyanohydrin.
