Bucky-bowls. A general approach to benzocorannulenes: synthesis of mono-, di- and tri-benzocorannulenes

Abstract

We outline a conceptually simple and general route to bowl-shaped benzocorannulenes based on readily assembled PAHs which on flash vacuum pyrolysis result in the sequential formation of a five- and six-membered ring; following this approach, syntheses of mono-, di- and tri-benzocorannulenes have been achieved.
