Development of a General Pd(II)-Catalyzed Intermolecular Hydroalkoxylation Reaction of Vinylphenols by Using a Sacrificial Alcohol as the Hydride Source
摘要:
A general hydroalkoxylation of vinylphenols has been successfully developed wherein primary, secondary, and tertiary alcohols can be used as nucleophiles. The key conceptual breakthrough is the use of sec-phenethyl alcohol at relatively low concentrations as the sacrificial alcohol to undergo oxidation and provide the proposed Pd-H intermediate.
