A NEW PALLADIUM-CATALYZED SYNTHESIS OF 1,2,3,4,4a,8b-HEXAHYDRO-1,4-METHANOBIPHENYLENES AND 2-PHENYLBICYCLOHEPT-2-ENES

Catellani, Marta,Chiusoli, Gian Paolo,Ricotti, Stefano

, p. C11 - C16 (1985)

Aromatic bromides react with bicyclohept-2-ene in the presence of palladium(0) coplexes and alkali phenoxides to give hexahydromethanobiphenylenes and phenylbicycloheptenes, probably via palladacyclic intermediates.Use of hindered phenoxides leads to selective cyclobutene ring closure.
