Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF3) is an organosilicon compound with the formula CF3Si(CH3)3. It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group. The compound was first prepared in 1984 … See more The reagent is prepared from trimethylsilyl chloride and bromotrifluoromethane in the presence of a phosphorus(III) reagent that serves as a halogen acceptor. See more In the presence of an anionic initiator (M X ), the reagent reacts with aldehydes and ketones to give a trimethylsilyl ether, the net product of insertion of the carbonyl into the Si-CF3 bond. Hydrolysis gives trifluoromethyl methanols. The reagent also converts esters … See more WebName : TRIFLUOROMETHYLTRIMETHYLSILANE CAS No : 81290-20-2 Name Product identifier % GHS-US classification Trifluoromethyltrimethylsilane (CAS No) 81290-20-2 95 - 100 Flam.
