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.
沿这种方式走:发现富勒烯可以在高温下热重排列为苯40多年后,人们发现在温和的条件下,6,6-二氰基戊烯富勒酸可以定量重排为1,3和1,4-二氰基苯。极性非质子溶剂。提出了一种极性“环游”机制来解释这种空前的反应性。
