In this paper, we report on conformationalstudies of biarylic compounds, as prepared through the well-known aza-Wittig methodology. The conformationalstudies were mainly realized by bidimensional (2D) nuclear magnetic resonance spectroscopy (NMR) and NOESY experiments. The conformational behavior showed that these biarylic compounds display an orthogonal symmetry and adopt a characteristic arrangement
