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.

A series of substituted 1,8-diarylnaphthalenes, II-X, has been prepared, and the barrier to rotation about the aryl-naphthalene bond has been measured. A monotonie increasing relationship between ΔG* and σpara values has been found. This is int
