1-(2,4-dichlorophenyl)butan-1-one

Conditions: temp:-20.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 2,4-dichlorobenzoyl chloride (4.5 g) and copper (I) iodide (200 mg) in dry THF (30 ml) was cooled to −20° C. under argon. Then a solution of n-propyl magnesium chloride (2 M in ether, 11.0 ml) was added dropwise. Ten minutes after addition was complete, the cooling bath was removed and the mixture stirred for 1 hour. Water was carefully added, followed by extraction with toluene. The toluene layer was washed with dilute HCl, water, saturated sodium bicarbonate solution, dried and concentrated in vacuo to give 1-(2,4-dichlorophenyl)butan-1-one (4.0 g). Ten minutes after addition the cooling bath was removed Water was carefully added followed by extraction with toluene The toluene layer was washed with dilute HCl, water, saturated sodium bicarbonate solution dried concentrated in vacuo
