When a very fast radical probe cyclization hints at a carbanionicintermediate rather than at a radical one: A further proof of a polarmechanismfor the aryl bromide-alkyllithium exchange reaction

A new, very fast aryl radical clock, the 2-bromophenyl 3-phenyl-2-propenyl ether 1, was reacted with n-BuLi in THF. A large amount of cyclized product was formed. Such a product could have arisen from an efficient cyclization of a radical formed by dissociation of the radical anion yielded by an ET...
