The synthesis of substituted 1,8-diarylnaphthalenes is reported. A bis-Suzuki coupling strategy starting from 1,8-dibromonaphthalene provides a useful and general route to the 1,8-diarylnaphthalene scaffold. In this context, N-heterocyclic benzhydrylamine ligands, in combination with PdCl2, were found to form especially efficient catalytic systems. The syn/anti ratios were determined in solution from their 1H NMR spectra. Analysis of the molecular structure in the solid state for six new targets focused on deformation of the naphthalene core. The observed lack of planarity occurs as a result of several parameters, such as the nature and number of substituents, the substitution pattern as well as steric congestion and π-stacking between cofacial rings. The synthesis of substituted 1,8-diarylnaphthalenes using bis-Suzuki coupling of 1,8-dibromonaphathalene is described. Molecular structures in the solid state for six new compounds were analyzed. The influence of several parameters on naphthalene core deformation are described.
