TEMPO (2,2,6,6-Tetramethylpiperidin-1-oxyl) is a stable free radical commonly used as an oxidizing agent in organic synthesis. Copper/TEMPO has been utilized in the catalytic oxidation of primary alcohols to aldehydes.
A highly efficient 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO) catalyzed reaction using recyclable 1-chloro-1,2-benziodoxol-3 (1 H)-one as the terminal oxidant allows the conversion of various alcohols to their corresponding carbonyl compounds in high to excellent yields at room temperature in ethyl acetate, which is an environmentally friendly...
Aug 29, 2022 · TEMPO, like DABCO, the Molecule of the Week for August 29, 2022, is one of those molecules best known by its acronym. TEMPO’s full name is 2,2,6,6-tetramethyl-1-piperidinyloxy. TEMPO is also unusual in that it is a stable free radical.
Mar 31, 2014 · The radical TEMPO (2,2,6,6-tetramethylpiperidine 1-oxyl radical) and its derivatives are well-established catalysts for oxidation processes, and now used extensively in organic synthesis and...
TEMPO is a member of the class of aminoxyls that is piperidine that carries an oxidanediyl group at position 1 and methyl groups at positions 2, 2, 6, and 6, respectively. It has a role as a ferroptosis inhibitor, a catalyst and a radical scavenger.
Aug 16, 2021 · 2,2,6,6-Tetramethylpiperidinyloxyl (TEMPO) is an organic nitroxyl which is widely used as a catalyst in electrochemical redox reactions.
May 18, 2009 · The radical TEMPO and its derivatives find a variety of industrial applications as highly selective oxidation catalysts for the production of pharmaceuticals, flavors and fragrances, agrochemicals,...
Feb 1, 2023 · 2,2,6,6-Tetramethylpiperidine-1-oxyl, commonly known as TEMPO, is one of the compounds called nitroxides that are used in the chemical industry for synthesis of many organic compounds as well as for electrodes in all-organic radical batteries.
TEMPO and related stabilized nitroxyl radicals have found wide application as catalysts in green oxidation technology for the synthesis of aldehydes and ketones. The actual oxidant, the oxonium ion, can be used in stoichiometric amounts, but this adds cost and poor atom economy.
Jan 18, 2023 · In this work, we give an insight into the local structure of ILs around TEMPO and its oxidized form, TEMPO +, underlining striking differences in the solvation of these two species. The analysis is coupled with a study of thermodynamics and kinetics of oxidation in the frame of Marcus theory.
