Abstract: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.
