Covalent organic frameworks (COFs) have garnered attention in visible light photocatalysis, with 2D COFs like Por-DETH-COF exhibiting high selectivity for the red light-driven oxidation of benzyl amines to imines. The COF photocatalyst displays remarkable functional group compatibility and a wide scope of benzyl amine substrates.
Covalent organic frameworks (COFs) have recently gained rising consideration for visible light photo catalysis. Their property could be accurately established with specific reactions in which the most investigated one turns out to be the aerobic oxidation of amines. In this contribution, a hydrazone-linked 2D (two-dimensional) porphyrinic COF, Por-DETH-COF, was assembled from 5,10,15,20-tetrakis(4-benzalde hyde)porphyrin (p-Por-CHO) and 2,5-diethoxyterephthalohydrazide (DETH) and its photocatalytic activity was duly appraised with the aerobic oxidation of amines. Thereby, the red light-driven selective oxidation of benzyl amines to imines was obtained in very high conversions and selectivities with ambient air as the oxidant. Importantly, the photocatalytic system exhibited remarkable compatibility of functional groups and extensive scope of benzyl amines. Notably, the Por-DETH-COF photocatalyst displayed outstanding recyclability after five successive cycles. This work suggests that 2D COFs could contribute a unique juncture for selective organic transformations by photocatalysis. (c) 2021 Elsevier Inc. All rights reserved.
