Synthesis and properties of the perfluoroethyl martin silicate: reactivity in solution and solid-state mechanochemistry

Abstract

We herein report the first synthesis of a Martin silicate bearing a pentafluoroethyl chain. The full characterisation of this new pentacoordinated silicon species is detailed. Insights on its electronic properties based on structural, physicochemical and computational data are provided. A comparative study of reactivity in solution and in solid state by mechanochemistry has been performed in order to assess the ability of this bench-stable salt to act as a safe C2F5-alkylation reagent in a nucleophilic or radical manner.
