Herein, the iron-catalyzed borylation of aryl ethers and aryl amines via cleavage of C-O and C-N bonds is reported. This protocol does not require the use of Grignard reagents and displays a broad substrate scope, which allows the late-stage borylation. It also provides facile access to multisubstituted arenes through C-H functionalization using 2-pyridyloxy as the directing group. In the experiment, the researchers used many compounds, for example, 2-Phenoxypyridine (cas: 4783-68-0Computed Properties of C11H9NO).
2-Phenoxypyridine (cas: 4783-68-0) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Many analogues of pyridine are known where N is replaced by other heteroatoms . Substitution of one C–H in pyridine with a second N gives rise to the diazine heterocycles (C4H4N2), with the names pyridazine, pyrimidine, and pyrazine.Computed Properties of C11H9NO
