Obtained by reaction of fluoroacetyl chloride with anisole in the presence of aluminium chloride in chloroform at r.t.
Also obtained by reaction of pyridinium poly(hydrogen fluoride) with 4-methoxy-a-diazo-acetophenone in ethyl ether at r.t. for 24 h (54%)
Also obtained by reaction of Selectfluor with 1-(4-methoxyphenyl)ethanone in boiling methanol for 24 h (71%)
Preparation by adding Rongalite to a solution of dichlorofluoromethyl 4-methoxyphenyl ketone in ethanol under nitrogen. Then, the solution was refluxing for 45 min (65%).
