GRAPHICAL ABSTRACT
ABSTRACT
An efficient protocol was developed for the synthesis of N-sulfonylimines under environment friendly conditions. Ultrasonic energy was employed to obtain the desired products in excellent yields with high purity under solvent- and catalyst-free conditions. The synthesis of new N-sulfonylimines was accomplished from various N-sulfonamides and benzaldehyde.
The structures of the synthesized compounds are confirmed by elemental analysis as well as by 1H, 13C NMR spectral data, IR and MS.
