资源简介：
The
reversible covalent binding of diols to an N-Bn 1,2-BN
cyclohexane has been studied by 11B and 1H NMR
spectroscopy and single-crystal X-ray diffraction analysis.
The activation barrier for the reversible B–N Lewis acid–base
interaction has been measured by variable-temperature NMR with bound
(2R,3R)-(−)-2,3-butanediol
(Tc = −40 °C, ΔG⧧ = 11.2 ± 0.2 kcal mol–1). Deuterium labeling experiments demonstrate that
ligand exchange is reversible and rapid at room temperature, and competitive
binding studies establish diol association as a thermodynamically
controlled process.
