Irradiation of 1,2,4,5-tetracyanobenzene in tetrahydrofuran underwent photosubstitution to give tetrahydro-2-(2,4,5-tricyanophenyl)furan. The reaction is scarecely affected by trifluoroacetic acid and hence it appears to belong to a novel class of photoelectrophilic substitution.

This study identifies a novel class of photoelectrophilic substitution reaction, where 1,2,4,5-tetracyanobenzene in tetrahydrofuran undergoes photosubstitution to produce tetrahydro-2-(2,4,5-tricyanophenyl)furan
