Electric Literature of C6H4ClNO. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 5-Chloropicolinaldehyde, is researched, Molecular C6H4ClNO, CAS is 31181-89-2, about Ligand-Free Iridium-Catalyzed Dehydrogenative ortho C-H Borylation of Benzyl-2-Pyridines at Room Temperature. Author is Yang, Yuhuan; Gao, Qian; Xu, Senmiao.
A convenient and ligand-free Ir-catalyzed dehydrogenative ortho C-H borylation of benzyl-2-pyridines was developed. The reaction proceeds smoothly at room temperature using pinacolborane as a borylating reagent in the presence of catalytic amount of [IrOMe(COD)]2. The reaction is compatible with many functional groups, providing a vast array of ortho borylated products in moderate to excellent yields with excellent selectivities.
