TTMS - Reference Information
| Background | since trifluoromethyltrimethylsilane (TMSCF3) in 1984 by CF3Br (an ozone depleting compound) and trimethylsilyl chloride compounds after 30 years of synthesis, various C- CF3 bond-forming reactions have been developed from various trifluoromethylating agents. TMSCF3 (Bruton-Prakash reagent) has a nucleophilic trifluoromethylating reagent that was and remains important with CF3 as the center. |
| Introduction | (trifluoromethyl) Trimethylsilane is a colorless transparent liquid that can be used as a trifluoromethylating agent, for aldehyde and ketone nucleophilic addition reaction. |
| Application | The Ruppert-Prakash reagent is now also a synthetic potassium (trifluoromethyl)-trimethoxyborate, well-defined trifluoromethyl copper compound, trifluoromethanesulfonamide/trifluoromethanesulfonamide for trifluoromethyl mercaptan, difluoromethyl trifluoromethanesulfonate as difluorcarbene (difluoromethyl) trimethylsilane (difluoromethyl) A suitable source of useful starting material for the silane (TMSCF2H) is used for the difluoromethylation reaction, and the Togni reagent and related species act as electrophilic trifluoromethylation reagents. |
| Use | (trifluoromethyl) Trimethylsilane is a reagent for trifluoromethylation of alkyl compounds. takes part in the nucleophilic addition reaction of trifluoromethyl groups to produce aldehydes and ketones. trifluoromethylating reagent, trifluoromethyl groups added to aldehydes and ketones. |
