Herein, we report a new and convenient methodology for the synthesis of ortho-XCF2 arylphosphonates via Diels–Alder reaction of selected 1,3-butadienes with XCF2–≡–P(O)(OEt)2, followed by the aromatization of the cyclic vinylphosphonates obtained using the KMnO4/Al2O3 system. The reactivity of ortho-XCF2 arylphosphonates was then examined to give the respective dichlorides that were converted to the
