1,1,1-trifluoro-4-(4-methylphenyl)but-3-en-2-one

Conditions: temp:0.00; pressure:0.00; stir:

Conditions: temp:22.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of toluene (8, R1=p-CH3, R3=R4=H, 10 mmol) and 4-ethoxy-1,1,1-trifluoro-3-buten-2-one (10 mmol) in dichloromethane (10 mL) is added zinc chloride (0.015 g, 1.5 mol %). The reaction mixture is stirred for 3 h at 22° C. The resulting precipitate is filtered, washed with dichloromethane (2×15 mL) and dried. The resulting precipitate is filtered washed with dichloromethane (2×15 mL) dried

Conditions: temp:22.01; pressure:0.00; stir:; See reaction.notes.procedure_details.
