Reaction Conditions:
with iron(III)-acetylacetonate in tetrahydrofuran at -20; for 1 h;Inert atmosphere;
Steps:
1
[0126] A solution of ethylmagnesium chloride (2 M in THF, 9.38 mL, 18.77 mmol) was added overmm to a solution of 4-(trifluoromethoxy)benzoyl chloride (11-1) (purity 98%, 5.00 g, 21.82 mmol)iron(III) acetylacetonate (385 mg, 1.09 mmol) in THF (70 mL) at -20°C under argon. After stirring10 mm at that temperature, the reaction mixture was quenched with 1 N HC1 and the mixture wasrepeatedly extracted with CH2C12. The combined organic layers were washed with 2 N NaOH, driedover Na2SO4 and evaporated to yield 1-[4-(trifluoromethoxy)phenyl]propan-1-one (111-1) (purity 90%,4.95 g, 93%). ‘H NMR (400 MHz, DMSO-d6) 1.09 (t, 3H), 3.07 (q, 2H), 7.50 (d, 2H), 8.10 (d, 2H).
