4-Fluorobenzaldehyde was easily synthesized from 4-chlorobenzaldehyde by potassium fluoride in the presence of tetraphenylphosphonium halide plus 18-crown-6 or poly(ethylene glycol) dimethyl ether. Several fluorobenzaldehyde derivatives were similarly prepared from the corresponding chloro-derivatives in good ...
