Abstract
Disclosed is a method for preparing a 2-iodoheterocyclic aryl ether at room temperature, including adding an alkali metal hydride and a phenol to a solvent, then adding a diiodoheterocyclic aromatic hydrocarbon, and performing a reaction at 0-100° C., so as to obtain a 2-iodoheterocyclic aryl ether product. In the coupling process of the present invention, no transition metal catalyst needs to be added, and no metal pollution will be caused to the product. The product of the present invention can be used as an organic synthesis raw material for a further reaction, and can also be used as an additive flame retardant reagent to improve the flame retardant performance of plastics.
