Yuan, Tao; Zheng, Meifang; Antonietti, Markus; Wang, Xinchen published the artcile< Ceramic boron carbonitrides for unlocking organic halides with visible light>, Category: chlorides-buliding-blocks, the main research area is boron carbonitride preparation surface structure; aryl halide boron carbonitride photocatalyst hydrodehalogenation; aromatic hydrocarbon preparation; arene aryl halide boron carbonitride photocatalyst cross coupling arylation; biaryl preparation; haloarene sodium sulfinate boron carbonitride photocatalyst cross coupling sulfonylation; arylsulfone preparation.
Here, boron carbonitride (BCN) ceramics were such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradn was reported. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds was proceeded at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN was used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst showed tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opened new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which were metal-free, inexpensive and stable.
