A wide range of functional aryl and heteroaryl zinc reagents have been efficiently prepared via regio- and chemoselective zincation using TMPZnCl.LiCl and microwave irradiation. Sensitive functional groups like esters are compatible with the high temperatures of the reactions. The resulting zinc species undergo a number of subsequent reactions, providing highly functionalized aromatics and heteroaromatics in high yields.
