| | 4'-(Trifluoromethyl)acetophenone Usage And Synthesis |
| Synthesis | 41.6 g of chlorocyclohexane (0.35 mol) were added dropwise to a suspension of 4.65 g of lithium particles (0.68 mol) in 350 g of THF at -55 °C, and an addition time of 2 hours was chosen. After >97% chlorocyclohexane conversion by GC (10 hours), a mixture of 38.3 g of 4-bromotrifluorotoluene (0.170 mol) and 7.0 g of acetonitrile (0.170 mol) was added dropwise at the same temperature for 15 minutes. After stirring for an additional 30 minutes at -50°C, the reaction mixture was slowly thawed to room temperature and subjected to an aqueous workup in a conventional manner. The yield of 4-trifluoromethylacetophenone after distillation was 81%. | | Chemical Properties | White to faintly yellow low melting solid | | Uses | A labelled acetophenone with selective antimycobacterial activity. | | General Description | The enantioselective addition of dialkylzinc to 4′-(trifluoromethyl)acetophenone mediated by 1,2-bis(hydroxycamphorsulfonamido)cyclohexenes in the presence of titanium tetraisopropoxide has been investigated. Phosphorescence emission spectra of 4′-(trifluoromethyl)acetophenone has been studied using pulsed source phosphorimetry. | | Purification Methods | Purify the ketone by distillation or sublimation in vacuo.[Beilstein 7 IV 1404.] |
