1,2,3,5-Tetrakis(carbazol-9-yl)-4,6-dicyanobenzene (4CzIPN)-based porous organic polymers for visible-light-driven organic transformations in water under aerobic oxidation
A novel and highly efficient gold(III)-complex catalyzed aerobic oxidative α-CâH functionalization of amines has been developed. The tertiary amines can be directly coupled with various nucleophiles using air as a sustainable oxidant.
An anthraquinone-containing polymericphotosensitizer (AQ-PHEMA) can catalyze the cross-dehydrogenative-coupling of N-aryl tetrahydroisoquinolines with several nucleophiles (nitromethane, 1-methyl-2-alkyl ketone and dialkyl (aryl) phosphine oxide) efficiently by visible light to afford a series of 1-substituted-2-aryl-1,2,3,4-tetrahydroisoquinolines in good to excellent yields with nice substrate tolerance

heterogeneous photocatalyst via a radical polymerization process is described, and its catalytic activity was evaluated for the aerobic phosphonylation reaction of N-aryl tetrahydroisoquinolines under visible light irradiation.
A scalable, efficient gold‐catalyzed oxidativephosphonation of sp3CHbonds with various diarylphosphine oxides and dialkyl phosphites has been developed by usingair as a sustainableoxidant under mild reaction conditions. It provides an easy access to α‐amino phosphonic compounds in high yields with a broad reaction scope. The safe, convenient and environmentally benign process makes this protocol
A photoelectrochemical cell is able to save nearly 90% external bias input to realize activation of P–H/C–H bonds for cross-coupling hydrogen evolution as compared with an electrochemical cell.
