Colorful chemistry: A series of 2H-cyclohepta[b]furan-2-one-substituted tetracyanobutadienes (TCBDs) were synthesized in one step by the [2+2] cycloaddition of tetracyanoethylene with the corresponding acetylene derivatives (see scheme). These new TCBDs were characterized by strong intramolecular charge-transfer absorptions in the UV/Vis spectra.
