How the strength of the N−H^δ+⋅⋅⋅^δ−H−B interaction and hence the DHB-driven self-aggregation of amine-borane adducts is governed by steric effects has been investigated by comparing the structures and binding enthalpies of various chiral derivatives. For a diastereomeric pair of amine-boranes prepared from a chiral secondary amine, it is shown that the stereochemistry at the nitrogen atom has a significant influence on the interaction enthalpy.

立体化学控制手性胺硼烷加合物中的双氢键强度

通过比较各种化合物的结构和结合焓，研究了N−H ^δ+ ⋅⋅⋅ ^δ −H−B 相互作用的强度以及 DHB 驱动的胺-硼烷加合物的自聚集如何受空间效应控制手性衍生物。对于由手性仲胺制备的一对非对映体胺-硼烷，表明氮原子的立体化学对相互作用焓有显着影响。
