Can non-polar hydrogen atoms accept hydrogen bonds?

Research output: Contribution to journalArticlepeer-review


We examine an unusual case where a neutral hydrogen atom
acts as a hydrogen-bond acceptor. The association constant
between trihexylsilane and perfluoro-tert-butanol was measured as
0.8 M-1 in cyclohexane. Computations and experimental NMR data
are consistent with a weak, but favourable Si–H HO interaction.
