%X A comparative study by NMR using designed top pan molecular balances demonstrates that the noncovalent interaction of a hydroxyl group with π-deficient pyrazine and quinoxaline units involves a lone pair•••heteroarene interaction which is much stronger and essentially solvent independent when measured relative to the classical π-facial hydrogen bond to a benzene ring. Alkyl fluorides also prefer the heteroarene rings over the benzene ring. The attractive interaction between a quinoxaline and a terminal alkyne is also stronger than the intramolecular hydrogen bond to an arene.
