摘要：

It is attractive to develop a durable and renewable carbon nitride-based photocatalytic system for compelling photocatalytic organic synthesis, but remains a huge challenge. In this study, cost-effective ultrathin carbon nitride nanosheets (denoted as CNS) with abundant active sites and visible light harvesting capacity were designed and prepared, with the aim of realizing the decarboxylation free radical coupling reaction between Narylglycine and aldehydes. The as-prepared catalyst enabled good to high yields (up to 97%) of 1,2-amino alcohols with a wide substrate range and desired functional group tolerance. Furthermore, CNS provided a longterm durability, and could be straightforwardly recovered through simple centrifugation of reaction solutions. In addition, this practical strategy is also applicable to gram-scale photosynthesis as well as the synthesis of some other complex molecules, providing an alternative to homogeneous organic photocatalysts for the synthesis of valuable pharmaceutical intermediates for future applications.
