Descripción

Descripción general

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

Aplicación

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.
