Highly Efficient Pd-Catalyzed Carbonylative Cross-Coupling Reactions with Tetraorganoindates. — Palladium-catalyzed carbonylative cross coupling of aryl(alkyl)
halides or triflates (I) and (VI) is smoothly achieved using tetraorganoindates (II) as
nucleophilic partner under carbon monoxide atmosphere. The reaction affords unsymmetrical ketones in moderate to good yields, and even diketones like (VIIg) are prepared by reaction of benzoyl chloride. Almost all of the organyl groups of the indate
(II) are transferred to the electrophilic partner. — (LEE*, P. H.; et al.; J. Org. Chem.
