Palladium Alkoxides: Potential Intermediacy in Catalytic Animation, Reductive Elimination of Ethers, and Catalytic Etheration. Comments on Alcohol Elimination from Ir(III)

摘要

Our group and those of Boncella and Hillhouse recently observed carbon-nitrogen and -sulfur bond-forming reductive eliminations of amines and sulfides from palladium and nickel amides and thiolates. These observations led to improvements in the palladium-catalyzed animation of aryl bolides. In contrast, analogous chemistry to form ethers and alcohols from palladium alkoxides has been elusive. Further, the potential intermediacy of palladium alkoxides in aryl halide animation chemistry has not been evaluated.
