General description
2,2,6,6-Tetramethylpiperidineis a hindered secondary amine that is used to prepare metallo-amide bases and selective generation of silylketene acetals.
Application
2,2,6,6-Tetramethylpiperidine can be used as a reactant to synthesize:
- Allylated tertiary amines via allylic amination of allylic chlorides.
- Hydroxylamines via oxidation in the presence of oxone as an oxidant.
- Sulfenamide compounds by reacting with heterocyclic thiols in the presence of iodine as an oxidant.
- N-methylated amines via N-methylation by reacting with CO2 and phenylsilane.
- Propargylamines via three-component Mannich coupling reaction with aldehydes and alkynes.

A Ca2+-crosslinked wood-based nanofibrillated cellulose (NFC) hydrogel was investigated to build knowledge toward the use of nanocellulose for topical drug delivery applications in a chronic wound healing context. Proteins of varying size and isoelectric point were loaded into the hydrogel

Nanocomposites of polyvinyl acetate (PVAc) reinforced with two different TEMPO-oxidized cellulose nanofibrils (CNF) were prepared by casting/evaporation method. These two sets of CNF, designed as CNF-O-5min (5min of oxidation) and CNF-O-120min (120min of oxidation), are different by their surface charge
