A visible light mediated, metal and oxidant free highly efficient cross dehydrogenative coupling (CDC) reaction between quinoxalin-2(1)-ones and ethers

The efficient and metal free, white light mediated 3C alkylation of quinoxalin-2(1 H )-ones via a cross dehydrogenative coupling reaction with cyclic ethers using eosin Y as a photocatalyst is described. This reaction has broad substrate scope and strong functional group tolerance with good to excel...

Summary:The efficient and metal free, white light mediated 3C alkylation of quinoxalin-2(1 H )-ones via a cross dehydrogenative coupling reaction with cyclic ethers using eosin Y as a photocatalyst is described. This reaction has broad substrate scope and strong functional group tolerance with good to excellent yields. The white light mediated, 3C alkylation of quinoxalin-2(1 H )-ones via a cross dehydrogenative coupling (CDC) reaction with cyclic ethers using eosin Y as a photocatalyst is described. The reaction proceeds via a hydrogen abstraction and transfer process.
