Abstract
A comparative study by NMR spectroscopy using molecular balances indicates that non-covalent functional group interactions with an arene dominate over those with an alkene and a p-facial intramolecular hydrogen bond from a hydroxyl group to an arene is favoured by ~1.2 kJ mol-1. The strongest interaction observed in this study is with the cyano group and analysis of the series of Et, CH=CH2, C≡CH and C≡N groups is indicative of a weak long range electrostatic interaction and a correlation with the electrophilicity of the Ca atom of the Y substituent. Changes in the free energy differences of conformers show a linear dependence on the solvent hydrogen bond acceptor parameter β.
