Dehydrogenation of Hexamethyl-Dewar-benzene to its Tetramethyl-o-dimethylene Derivative: Synthesis and Cycloreversion of 1,2,3,4-Tetramethyl-5,6-bismethylenebicyclo[2.2.0]hex-2-ene
The allylic bromination of hexamethyl-Dewar-benzene (1) followed by dehydrobromination yields tetramethyl-Dewar-«xylylene» (3). The cycloreversion of 3 to the reactive monocyclic isomer 4 proceeds smoothly upon irradiation or heating above 60 °C.
