Significance
The authors report a synthesis of a variety of interesting materials using tandem thermal [2+2]-cycloaddition-retro-electrocyclization reactions. The reaction is high-yielding, atom-economical, and selective; electron-poor tetracyanoethylene (TCNE) and the electron-rich tetrathiafulvalene (TTF) show selectivities for electron-rich and electron-poor alkynes, respectively.
