Applications & Uses
Uses
3-Bromopyridine undergoes lithiation with LDA at low temperatures in the 4-position: Heterocycles, involved in formation of the Grignard by Mg exchange with i-PrMgCl and in transmetallation of the lithiated derivative with zinc chloride followed by treatment with an electrophile as a route to 4-substituted 3-bromopyridines.
Uses
Pyridine as novel substrate for regioselective oxygenation with aromatic peroxygenase from Agrocybe aegerita.
