Walk this way: More than 40 years after the discovery that fulvene can thermally rearrange to benzene at high temperatures, it has been found that 6,6-dicyanopentafulvenes can rearrange quantitatively to 1,3- and 1,4-dicyanobenzenes under mild conditions in polar aprotic solvents. A polar ring-walk mechanism is proposed to explain this unprecedented reactivity. Copyright
