Interweaving Visible-Light and Iron Catalysis for Nitrene Formation and Transformation with Dioxazolones

Herein, visible-light-driven iron-catalyzed nitrene transfer reactions with dioxazolones for intermolecular C(sp3)-N, N=S, and N=P bond formation are described. These reactions occur with exogenous-ligand-free process and feature satisfactory to excellent yields (up to 99 %), an ample substrate scope (109 examples) under mild reaction conditions. In contrast to intramolecular C?H amidations strategies, an intermolecular regioselective C?H amidation via visible-light-induced nitrene transfer reactions is devised. Mechanistic studies indicate that the reaction proceeds via a radical pathway. Computational studies show that the decarboxylation of dioxazolone depends on the conversion of ground sextet state dioxazolone-bounding iron species to quartet spin state via visible-light irradiation.

Method for synthesizing phosphinimide compound

The invention relates to a method for synthesizing a phosphonimide compound, and belongs to the field of metal catalytic organic synthesis. The method for synthesizing the phosphonimide compound comprises the following steps: adding an N-hydrocarbon acyloxy amide derivative, tertiary phosphine, a catalyst and an organic solvent into a reaction container, carrying out a reaction at a room temperature in an air atmosphere, and after the reaction is completed, carrying out post-treatment so as to obtain the phosphinimide compound. The method for synthesizing the phosphonimide compound disclosed by the invention has the following beneficial effects: (1) the range of a substrate is wide; (2) the catalyst is relatively low in price and less in usage amount; (3) the reaction operation is simple;and (4) the reaction yield is high, and high yield can still be obtained when the reaction is amplified to a gram level.
