Palladium-catalyzed Cross-coupling of Aryl Iodides with beta-Trimethylsiloxy-alpha-diazoesters: A Novel Approach toward beta-Keto-alpha-arylesters
Palladium-catalyzed cross-coupling of beta-trimethylsiloxy-alpha-diazoesters with aryl iodides provides a new approach to beta-keto-alpha-arylesters. It is shown that the beta-trimethylsiloxy group can significantly suppress the direct 1,2-hydride shift from palladium carbene.
