Polyfunctional bis-arylzinc reagents are accessible via a new lithium acetylacetonate-catalyzed iodine-zinc exchange. This protocol tolerates sensitive functional groups (ketones, aldehydes or isothiocyanates) in the aryliodides and allows the formation of highly functionalized zincreagents. These zincreagents can be used in a variety of catalyzed and uncatalyzed transformations.
