Abstract

Abstract : A magnetically separable graphitic carbon nitride nanocomposite (Fe3 O4 /g‐C3 N4 ) as a catalyst for the three‐component condensation reactions of carbonyl compounds, amines and trimethylsilylcyanide was thoroughly investigated. The reaction of these three components was found to be efficient, economical and green and took place in the presence of a catalytic amount of the magnetically separable catalyst to yield the corresponding α‐aminonitriles in good to excellent yields. The prepared nanocomposite was characterized using scanning electron microscopy and energy‐dispersive X‐ray and Fourier transform infrared spectroscopies. The nanocomposite was also found to be reusable could be recovered easily and reused several times without distinct deterioration in its catalytic activity. Abstract : A novel and practical one‐pot synthesis of α‐aminonitriles has been achieved by a three‐component condensation of aldehydes, amines and trimethylsilyl cyanide in the presence of magnetically separable g‐C3 N4 hybrid nanocomposit under mild conditions. The products were obtained in good to high yields and in short reaction times and the nanocatalyst could be recovered and reused for a minimum of five times without loss of activity.
