Abstract

Abstract : A TiO2 –Co ascorbic acid nanohybrid as an efficient photocatalyst catalyzed the selective synthesis of N -hydroxyimide esters through visible light irradiation. Abstract : In this study, we performed a visible light-mediated aerobic photo-cross dehydrogenative coupling (CDC) reaction between aldehydes and N -hydroxyimides using TiO2 –AA–Co as a photocatalyst for the synthesis of active esters. The synergistic and selective effects of the cobalt ascorbic acid complex (Co–AA) and TiO2 nanoparticles on the visible-light photocatalytic activity were explored. The method possesses some advantages such as environmentally friendly conditions, easy work-up procedure, reusability, and scalability.
