Crystalline triafulvalene derivatives of type 1 are obtained by treatment of dichlorodiarylcyclopropabenzenes with n ‐butyllithium in tetrahydrofuran at −78°C. The reaction presumably proceeds via the intermediacy of a carbene. Compound 1 is poorly soluble in the conventional solvents and exhibits a strong yellow fluorescence at 55 nm in CS 2 .
