Method for preparing bromo reagent by oxidative bromination reaction and method for further preparing bromine-containing compound

The invention relates to a method, and for preparing a bromine-containing compound through a reaction, of a :electron-substituted furan compound.rich electron-substituted furan compound, rich in an electron-rich substituted thiophene compound: The substituent of,rich electron-substituted furan compound containing, of an electron-rich substituted furan compound . The method for preparing the bromine-containing compound by the reaction of the present invention comprises the following steps. preparing an electron-rich substituted furan), compound (by). reacting with a bromine, containing substituted phenyl group, (.rich, electron-substituted furan compound and an aromatic or unsaturated bond-containing compound with an electron-rich substituted furan compound containing an electron-rich substituted furan compound.

BROMINATION OF KETONES AND PHENOLS WITH 4-(TRIBROMOMETHYL)QUINAZOLINE

4-(Tribromomethyl)quinazoline, 1, in benzene behaves as a brominating agent towards ketones (in the enol form) and phenols.The reaction has the features of a polar reaction, notwithstanding the nature of the solvent.Ketones and phenols behave as nucleophiles, and attack a bromine atom of the brominating agent.
