General description
Tetramethylammonium chloride is a quaternary ammonium salt commonly used as a catalyst due to its thermal stability and also tolerance towards strong aqueous bases or nucleophiles.
Application
Tetramethylammonium chloride along with N-hydroxyphthalimide and xanthone may be used as an efficient chloride catalytic system for the aerobic oxidation of hydrocarbons to form the corresponding oxygenated compounds. It may also be used as a phase transfer catalyst for the synthesis of aryl fluorides via selective chloride/fluoride exchange reaction of activated aryl chlorides with potassium fluoride in solid-liquid phase.

A solid understanding of the molecular-level mechanisms responsible for zeolite crystallization remains one of the most challenging issues in modern zeolite science. Here we investigated the formation pathway for high-silica LTA zeolite crystals in the simultaneous presence of tetraethylammonium (TEA(+))
