Exploring the anodic reaction to substitute conventional oxygen evolution reaction (OER) for the synthesis of complex pharmaceutical molecules is highly attractive. Here, we report an electrocatalytic strategy for dehydrogenative [4+2] cycloaddition of N,N-dialkylanilines with maleimides via dual functionalization of both C(sp 3 )-H and C(sp 2 )-H bonds, by using an electrochemically activated cobalt carbonate hydroxide hydrate supported on carbon cloth (CCHH-A/CC), affording various tetrahydroquinolines with high yields. This electrochemical transformation proceeds with high activity and stability, as well as good substrate compatibility. Mechanism study shows that α-aminoalkyl radical exists in the electrooxidation reaction. This strategy shows significant potential for the synthesis of valuable chemicals by using an electrocatalytic strategy.
A convenient, green, and scalable production approach to adsorbents with large adsorption capacity and cost-effective is exceedingly desirable yet challenging. Herein, a unique hierarchical zinc-aluminum layered double hydroxide (ZnAl-LDH-D) is...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
