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

Native wood celluloses can be converted to individual nanofibers 3-4 nm wide that are at least several microns in length, i.e. with aspect ratios>100, by TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl radical)-mediated oxidation and successive mild disintegration in water.

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

TEMPO Catalyzed Oxidations

TEMPO (2,2,6,6-Tetramethylpiperidinyloxy or 2,2,6,6-Tetramethylpiperidine 1-oxyl) and its derivatives are stable nitroxy radicals used as catalysts in organic oxidation reactions. TEMPO was discovered by Lebedev and Kazarnovskii in 1960. The stable free radical nature of TEMPO is due to the presence of bulky substituent groups, which hinder the reaction of the free radical with other molecules.

A Micro Review of Reversible Addition/Fragmentation Chain Transfer (RAFT) Polymerization

We presents an article about a micro review of reversible addition/fragmentation chain transfer (RAFT) polymerization. RAFT (Reversible Addition/Fragmentation Chain Transfer) polymerization is a reversible deactivation radical polymerization (RDRP) and one of the more versatile methods for providing living characteristics to radical polymerization.
