A new and practical process leading to 4-aryloxy-2,3,5,6-tetrafluorobenzaldehydes has been developed. The title skeleton is assembled in a convergent fashion from phenols and pentafluorobenzaldehyde via a nucleophilic substitution in the presence of inorganic fluorides. Scope and limitation studies have been conducted, revealing that the methodology is diversity tolerant, facilitating the introduction of various aryl and heteroaryl substituents. Altogether, 12 aldehydes were prepared in 14-93% yield.
