A Rh-catalyzed benzo/[7+1] cycloaddition of cyclopropyl-benzocyclobutenes (CP-BCBs) and CO to benzocyclooctenones has been developed. In this reaction, CP-BCB acts as a benzo/7-C synthon and the reaction involves two C-C bond cleavages: a thermal electrocyclic ring-opening of the four-membered ring in CP-BCB and a Rh-catalyzed C-C cleavage of the cyclopropane ring.

1-Alkenylbenzocyclobutenols, prepared from benzocyclobutenones via the addition of alkenyl Grignard reagents or the addition of alkynyllithium reagents followed by (E)-selective reduction, undergo successive thermal 4π and 6π electrocyclisations to give substituted 3,4-dihydro-1(2H)-naphthalenones. An analogous sequence gave 3,4-dihydro-1(2H)-anthracenone from naphtho[b]cyclobuten-1(2H)-one.

1-Alkenylbenzocyclobuten-1-ols, prepared from benzocyclobutenones via the addition of alkenylmagnesium bromides, or the addition of alkynyllithium reagents followed by (E)-selective reduction of the triple bond, undergo successive thermal 4π and 6π electrocyclic reactions leading to substituted 3,4-dihydro-1(2H)-naphthalenones.
