Visible light promoting the synthesis of phosphinimides catalyzed by TiO2

Phosphinimides are widely used in organic synthesis, biomedicine, polymer compounds and other fields. It is of great scientific significance to develop a new efficient and green method synthesis for the synthesis of phosphinimides. In this paper, visible light-induced TiO2-catalyzed the reaction of triphenylphosphine compounds with 3-aryl-1,4,2-dioxole-5-one for the synthesis of phosphinimides at room temperature was described, and the highest yield was up to 97%. The structure of the product was characterized by 1HNMR and 13CNMR. The reaction has the advantages of mild conditions, green and high efficiency.
