Modification of Palladium (II) Catalysis for Selective Partial Oxidation of Alcohols with Multifunctional Pyridylsiloxane Ligands
نویسندگان
چکیده
Introduction Aerobic catalytic oxidation is much more environmentally friendly than oxidation using stoichiometric oxidants. The Pd(OAc)2/pyridine system is active for the catalytic oxidation of primary and secondary alcohols to aldehydes and ketones, which are valuable for fine chemicals synthesis. Pyridine stabilizes the monomeric Pd complex and promotes its aerobic reoxidation to Pd prior to the formation of Pd-Pd bonds. Recently, a silica-supported Pd-bipyridyl complex was reported to be active for this catalytic process, and could be recycled several times.

متن کاملLigand-modulated palladium oxidation catalysis: mechanistic insights into aerobic alcohol oxidation with the Pd(OAc)(2)/pyridine catalyst system.
Pd(OAc)(2):pyridine (1:4) is an efficient catalyst system for the oxidation of alcohols with molecular oxygen. A mechanistic study of this reaction reveals that pyridine promotes the aerobic oxidation of palladium(0) but inhibits the oxidation of alcohol by palladium(II). Kinetic results reveal that turnover-limiting substrate oxidation consists of (i) formation of a palladium(II)-alkoxide, (ii...
