Triacetoxyperiodinane → 1-(4-Bromo-2-methylphenyl)-2,2,2-trifluoroethan-1-one

Participants

Reaction Steps

To a solution of 1-(4-bromo-2-methylphenyl)-2,2,2-trifluoroethanol (1.8 g, 6.7 mmol) in CH2Cl2 (20 mL) was added Dess-Martin Periodinane (3.4 g, 8.1 mmol) at 0° C. The mixture was stirred at RT for 2 h, then diluted with water (10 mL) and filtered. The filtrate was extracted with CH2Cl2. The combined organic layer was washed with brine, dried over Na2SO4 and concentrated in vacuo. Purification by normal phase silica gel column provided 1-(4-bromo-2-methylphenyl)-2,2,2-trifluoroethanone as a yellow oil.
