Photocatalytic Synthesis of Diphosphorous Quinoline Compounds

Abstract

Abstract Herein, we report the reaction of quinoline with diphenylphosphine oxide in the presence of visible light without catalyst. The reaction completes in 24 h under the mild conditions and the substrates are well tolerant. This method provides a straightforward and environmentally friendly access to diphosphorous quinoline compounds. Similarly, this method can also aid in the phosphate functionalization of some heterocyclic compounds.
