A new borylstannane was invented to achieve the radical borylation of various alkyl radical precursors. Various alkyl radical precursors including isocyanides, selenides, sulfides, and alcohol or carboxylic acid derivatives are found to be applicable to the present borylation. The cover picture of a trapeze performer (borylstannane) grasping the arms of a clown (a radical) depicts the transition state of the radical borylation. The arms of the performer show a vacant p ‐orbital on the boron atom of the borylstannane, which intends to capture the clown's arms (radical), and the fallen hat depicts a stannyl radical.
