Description

General description

Trimethylpentafluoroethylsilane ((Pentafluoroethyl)trimethylsilane) is a perfluoroalkylsilane. Alkyl triflates undergo nucleophilic pentafluoroethylation with trimethylpentafluoroethylsilane to form the corresponding pentafluoroethylated alkanes.

Application

Trimethylpentafluoroethylsilane ((Pentafluoroethyl)trimethylsilane) may be used as a perfluoroalkylating reagent for the synthesis of the following quinoline derivatives:

• 5-bromo-2-(perfluoroethyl)quinoline
• 8-methoxy-2-(perfluoroethyl)quinoline
• 1-(perfluoroethyl)isoquinoline
• 8-(tert-butoxy)-5,7-dichloro-2-(perfluoroethyl)quinolone

It may also be used in the synthesis of pentafluoroethylcyclohexanes.

Trimethylpentafluoroethylsilane has been reported as a Ruppert-Prakash type reagent for the addition of pentafluoroethane. Recent report by Larionov and coworkers displayed the feasibility of adding pentrafluoroethane to N-heterocycles under basic conditions.
