    Chlorobenzaldéhyde — Wikipédia

    Le 4-chlorobenzaldéhyde est une matière première pour la synthèse de pesticides chlorobenzilate, coumachlore, paclobutrazol, triticonazole et uniconazole. Partant du 2-chlorobenzaldéhyde, le clomazone est obtenu [6]. Le 4-chlorobenzaldéhyde peut également être utilisé pour la préparation du 4-fluorobenzaldéhyde [7].

    An improved and practical synthesis of 4 .

    A process which can afford a large quantity of 4-fluorobenzaldehyde was developed from halogen-exchange of 4-chlorobenzaldehyde with potassium fluoride in aromatic hydrocarbon solvents in the presence of tetraphenylphosphonium bromide plus polyethylene glycol dimethyl ether. The features of the reaction are discussed.

    The reaction is pretty straight-forward for a compound like this, but there are a few differences. The first step is the Henry condensation of 4-fluorobenzaldehyde with nitroethane, which goes in moderate yield with n-butylamine as catalyst under reflux.Using ethylenediammonium diacetate as catalyst at room temperature results in a miniscule yield.
