Descrição geral

2,2,6,6-Tetramethylpiperidineis a hindered secondary amine that is used to prepare metallo-amide bases and selective generation of silylketene acetals.

Aplicação

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 novel one-pot methodology is described for the synthesis of functionalized pyrrolopyridinones using in situ generated formimines and an ortho-lithiated pyridinecarboxamide species. Depending on the reaction conditions, this procedure allows versatile access to aminomethylated pyridinecarboxamides, 2,3-dihydro-pyrrolopyridinones, or 1,1-dialkylated 2,3-dihydro-pyrrolopyridinone derivatives.

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). Results
