Application

Catalytic oxidant for copper-catalyzed, greener oxidation of alcohols under aerobic conditions.

Copper(I)/TEMPO-catalyzed aerobic oxidation of primary alcohols to aldehydes with ambient air

TEMPO (2,2,6,6-Tetramethyl-1-piperidinyloxy) was used for trapping the styrenyl radical generated from benzoyl peroxide during nitroxide-mediated radical polymerization of styrene. TEMPO-mediated oxidation was employed for the carboxylation of water-resistant nanofibrillated cellulose (NFC) films.

General description

Copper/TEMPO has been utilized in the catalytic oxidation of primary alcohols to aldehydes.
