Tian, Miao published the artcileCovalent Organic Frameworks: A Sustainable Photocatalyst toward Visible-Light-Accelerated C3 Arylation and Alkylation of Quinoxalin-2(1H)-ones, HPLC of Formula: 55687-19-9, the main research area is quinoxalinone green arylation alkylation covalent organic framework photocatalyst; alkylation; arylation; covalent organic frameworks; quinoxalin-2(1H)-ones; visible-light-driven.
A practical and scalable protocol for visible-light-accelerated arylation and alkylation of quinoxalin-2(1H)-ones I (R = H; R1 = H, 8-Cl, 6,7-di-Me, 5-Cl, etc.; R2 = H, Me, Bn) with hydrazines RNHNH2 or RNHNH2•X (X = HCl, HOOCCOOH) is reported. In this protocol, a hydrazone-based two-dimensional covalent organic framework (2D-COF-1) was employed as the heterogeneous photocatalyst (PC). Due to its excellent photocatalytic properties, good chem. stability and heterogeneous nature, the present method exhibits high efficiency, good functional group tolerance, easy scalability and remarkable catalyst reusability. More importantly, it provides an alternative way that allows rapid access to various C3 arylated or alkylated quinoxalin-2(1H)-ones I (R = Ph, Et, cyclopentyl, etc.) in a greener and sustainable manner.
