General description

For a synthetic protocol using NMP initiators, contributed by Prof. Karen Wooley, please visit our technology spotlight.

Application

Stable nitroxide radical useful in controlling living polymerizations
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.

Various mechanical disintegration conditions in water were applied to 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose to prepare TEMPO-oxidized cellulose nanofibrils (TOCNs) of uniform widths ∼4 nm but with three different average lengths, 200, 680, and 1100 nm. The viscosity average degrees of polymerization

Homogeneous Cu/TEMPO catalyst systems (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) have emerged as some of the most versatile and practical catalysts for aerobic alcohol oxidation. Recently, we disclosed a (bpy)Cu(I)/TEMPO/NMI catalyst system (NMI = N-methylimidazole) that exhibits fast rates and high selectivities, even

Imidazolium salts bearing TEMPO groups react with commercially available copper powder affording Cu-NHC complexes. The in situ generated Cu-NHC-TEMPO complexes are quite efficient catalysts for aerobic oxidation of primary alcohols into aldehydes. The catalyst is easily available, and various primary
