ruthenium-based magnetically recoverable photoredox nanocatalyst with a large surface area. This visible light harvesting nanocatalyst was effectively used for cross-dehydrogenative coupling via C–H activation between tertiary amines and various carbon nucleophiles with high regioselectivity to afford the C–C coupled products in good to excellent yield using air as an oxidant under ambient conditions. The
The combination of vanadium- and organocatalysis allows for the direct oxidative coupling of cyclic tertiary amines with non-activated ketones without the need for preformed leaving groups.
钒催化和有机催化相结合,使得环状叔胺与非活化酮类无需预先形成的离去基团,即可直接进行氧化偶联。

and molecularly tunable optoelectronic properties, conjugatedmicroporouspolymers (CMPs) have been receiving increasing attention and research interest as promising alternatives to traditional inorganic semiconductors for heterogeneous photocatalysis. Herein, we report the concise synthesis of tetrathienoanthracene-based conjugatedmicroporouspolymers (TTA-CMP) via a bottom-up strategy. TTA-CMP was
