Palladium-Catalyzed Oxidation of Primary and Secondary Allylic and Benzylic Alcohols
摘要:
An efficient procedure for the oxidation of primary and secondary allylic and benzylic alcohols to aldehydes and ketones, respectively, has been achieved using catalytic Pd(OAc)2 in dimethyl sulfoxide (DMSO) with oxygen gas as the sole reoxidant of the palladium. Secondary substrates show increased reaction rates and improved yields with the addition of 2 equiv of NaHCO3. The reactions are free of acetal/ketal and ester byproducts.
