TRIMETHYLSILYL CHLOROSULFONATE

What is TRIMETHYLSILYL CHLOROSULFONATE?

Trimethylsilyl chlorosulfonate may be used:

in the sulfonation of small organic molecules
in the synthesis of sulfonated polysulfone
as sulfonating agent in the preparation of nano-structured organic-inorganic membranes for proton exchange membrane fuel cells (PEMFC) based on methacrylate and epoxy polymeric structures
in the preparation of sulfonated polysulfone (sPS)/titanium dioxide (TiO₂) composite membranes for use in PEMFCs
in the preparation of iodosobenzene sulfate, required for the synthesis of cyclic sulfates

Trimethylsilyl chlorosulfonate is commonly employed as sulfonating agent.
