1,1-Dibromoalkanes as bromocarbene sources make one-carbonringexpansion of indoles and pyrroles facile, allowing for direct access to structurally diverse azines, especially the pharmaceutically important 3-fluorinated quinolines and pyridines. This straightforward protocol features bench-stable reagents, a broad range of substrates, and good compatibility with various functional groups.
