The pale yellow title compounds undergo reversible photochemical conrotatory electrocyclic reactions to give in quantitative yields deep red 7,7a-dihydrobenzofuran-5,6-dicaroxylic anhydrides, which are stable at 100 deg C.These photochromic systems, which have high quantum yields for photocolouration, are highly resistant to photodegradation and retain their photochromic properties in a variety of solvents.
