一般描述

Trimethyl(trifluoromethyl)silane (TMSCF3) is also called as Ruppert-Prakash fluorination reagent. It is extensively used for the synthesis of trifluoromethyl-containing compounds.

应用

Reactant for:
  • Silver-mediated C-H trifluoromethylation of arenes
  • Preparation of trifluoromethyl ketone analog of L-arginine having contrasting inhibitory activity against human arginase I and histone deacetylase 8
  • Organocatalyzed regio- and enantioselective allylic trifluoromethylation of Morita-Baylis-Hillman adducts
  • Palladium-catalyzed oxidative trifluoromethylation of indoles
  • Preparation of 5-HT1A antagonists

  • Used as difluorocarbene source
TMSCF3 can be used as a reagent for:
  • Conversion of aromatic aldehydes to difluoromethylated products.
  • C-H trifluoromethylation of arenes, terminal alkynes, tertiary amines, heteroarenes, allylic, and terminal alkenes using metal catalyst or metal free oxidative trifluoromethylation reaction.

It can also be used in trifluoromethylation of:
  • Non-activated aldimines.
  • Heterocumulenes.
  • Azomethine imines.
