Abstract
A new and effective protocol driven by visible light has been introduced for the first time to synthesize 2-benzoxazolecarboxamides from benzoxazinones and amines in the presence of a conjugated microporous polymer, PATP. The reaction produced a variety of 2-benzoxazolecarboxamides in moderate to good yields while demonstrating excellent functional group tolerance under mild conditions. In comparison with transition metal complexes or organic dye molecules, PATP exhibited superior catalytic activity due to its extended π-conjugation system, porous structure, and electronic donor–acceptor (D-A) characteristics. Moreover, the polymer PATP showed consistent recyclability without any significant loss of photocatalytic efficiency after recovery.
