heterogeneous catalytic approach for selective coupling of C1 of N-aryltetrahydroisoquinolines with C3 of indoles in the presence of mesoporous manganese oxides. Our work involves a detailed mechanistic investigation of the reaction on the catalyst surface, backed by DFT computational studies, to understand the superior catalytic activity of manganese oxides.
A metal‐ and reagent‐free, electrochemical cross‐dehydrogenative couplingreaction of N‐aryl‐tetrahydroisoquinolines with phosphites and indole was reported, providing an environmentally benign and simple approach for the construction of C–P and C–C.

A luminescent MOF containing an AIE-active TPE moiety works as a selective sensor for detecting nitroaromatic explosives, as well as an efficient heterogeneous photocatalyst for CDC reactions mediated by visible light.
A novel stable radical cation triarylaminiumsalt able to induce aerobic oxidative α-C–H functionalization of tertiary amines in catalytic amounts has been developed. The reaction is performed in the absence of any other additives under mild conditions and only requires atmosphere air as a sustainable co-oxidant.
