Pd-Catalyzed Annulation of 1-Halo-8-arylnaphthalenes and Alkynes Leading to Heptagon-Embedded Aromatic Systems

A palladium-catalyzed heptagon-forming annulation reaction between 1-halo-8-arylnaphthalene and diarylacetylene is reported. The reaction is promoted using a catalytic system comprised of Pd(OAc)2, moderately electron-deficient triarylphosphine P(4-ClC6H4)3, and Ag2CO3 to afford benzo[4,5]cyclohepta[1,2,3-de]naphthalene derivatives in moderate to good yields, in preference to fluoranthene as a competing byproduct. Twofold annulation can also be achieved to access a novel heptagon-embedded polycyclic aromatic hydrocarbon compound.

Through-space control of the persistence of photogenerated o-quinonoid intermediates in naphthalenes containing cofacially oriented chromenes and arenes

Remarkable modulation of the persistence of the photogenerated colored o-quinonoid intermediates via a through-space interaction has been demonstrated in chromenes 1-4 based on 1,8-diarylnaphthalenes. Polar/π interaction is shown to stabilize the closed form of 4 to such an extent that photoinduced coloration is virtually invisible, while the same stabilization in the opened form of 2 permits ready coloration with a long-lived o-quinonoid intermediate.
