equivalent for the activation of molecular oxygen. The unique
property of TBN enabled TEMPO-catalyzed aerobic alcohol
oxidation to be performed in high-volume efficiency. Up to
a 16 000 turnover number was achieved in this transition-metal-free aerobic catalytic system. Under the optimal
reaction conditions, various alcohols were converted into
their corresponding carbonyl compounds with TEMPO/HBr/TBN as catalyst. The newly developed method was suitable
for the oxidation of solid substrate alcohols with high melting
point and/or low solubility under the help of minimum
solvent to form a slurry.
