A new synthetic route to symmetrical photochromic diarylperfluorocyclopentenes

Symmetrical and photochromic diarylperfluorocyclopentene has been prepared by reaction of 3-lithio-5-chloro-2-methylthiophene with the ethyl ester of hexafluoroglutaric acid, followed by ring closure via a McMurry coupling. Compound 7 is a versatile intermediate for the development of photochromic materials.
