Photoinduced Radical Coupling for Si-N Bond Formation

As an important class of compounds, silazanes serve as functional molecules in a variety of fields. Herein, we report a visible-light-induced radical-radical coupling of polysubstituted silanes with NHPI esters to achieve Si-N bond formation. This reaction produces a wide range of silazanes in good yields. Mechanistic studies suggest the involvement of silyl and nitrogen-centered radicals. This strategy provides a practical and general approach for constructing structurally diverse silazanes, which is potentially valuable for the development of functional materials.
