Beschreibung

Allgemeine Beschreibung

Sodium trifluoroacetate is a trifluoromethylating agent for compounds like aromatic halides, aldehydes and ketones.

Anwendung

Sodium trifluoroacetate can be used:

• As a trifluoromethylating agent in nucleophilic trifluoromethylation of aldehydes using copper(I) halide catalyst.
• As a difluorocarbene precursor in gem-difluorocyclopropanation of different alkenes using azobisisobutyronitrile (AIBN) as a catalyst.
• In the synthesis of trifluoromethylthio-substituted aromatic compounds via copper-mediated oxidative trifluoromethylthiolation of aryl boronic acids in the presence of elemental sulfur.
