Dong, Wenbo published the artcileA highly stable all-in-one photocatalyst for aryl etherification: the NiII embedded covalent organic framework, Category: isoquinoline, the main research area is photocatalyst aryl etherification cross coupling nickel covalent organic framework.
The efficient conversion of aryl bromides to the corresponding aryl alkyl ethers by dual Ni/photocatalysis has seen great progress, but difficulties of recycling the photosensitizer or Ni complexes cause problems of sustainability. Here, the authors report the design of a novel, highly stable vinyl bridge 2-dimensional covalent organic framework (COF) containing Ni, which combines the role of photosensitizer and reactive site. The as-prepared sp2c-COFdpy-Ni acts as an efficient heterogeneous photocatalyst for C-O cross coupling. The sp2c-COFdpy-Ni can be completely recovered and used repeatedly without loss of activity, overcoming the limitations of the prior methods. Preliminary studies reveal that strong interlayer electron transfer may facilitate the generation of the proposed intermediate sp2c-COFdpy-NiI in a bimol. and self-sustained manner. This all-in-one heterogeneous photocatalyst exhibits good compatibility of substrates and tolerance of functional groups. The successful attempt to expand the 2-dimensional COFs with this new catalyst into photocatalytic organic transformation opens an avenue for photoredox/transition metal mediated coupling reactions.
