One-shot TEMPO-periodate oxidation of native cellulose

Carbohydrate Polymers, 2019
TEMPO/NaClO/NaBr and sodium periodate were combined in a one-shot reaction to oxidise cellulose from bleached pulp. Oxidation of cellulose forms two fractions: a highly-carboxylated water-insoluble (up to 1.9 mmol COO-/g, DS = 0.39) and a water-soluble fraction (up to 4 mmol COO-/g, DS = 1.1).

Heterogeneous Cu–Mn oxides mediate efficiently TEMPO-catalyzed aerobic oxidation of alcohols

Catalysis Letters, 2006
Cu–Mn oxides in combination of 2,2,6,6-tetramethyl-piperidyl-1-oxy (TEMPO) were firstly used to catalyze aerobic selective oxidation of alcohols to carbonyl compounds. Such recyclable heterogeneous cocatalysts showed good catalytic performance in the process when the molar ratio of Cu and Mn is over 1.

Composite Photoelectrocatalysts for Tempo-mediated Alcohol Oxidations

ECS Meeting Abstracts, 2017
The transformation of primary alcohols to higher valuable carbonyls or acids has attached enormous attention from both academic and industrial viewpoints, but typically requires stoichiometric oxidants, which are costly and generate potentially toxic waste.
