A new six-membered cyclic frustrated phosphane/borane Lewis pair was liberated from its HB(C F ) adduct by treatment with vinylcyclohexane. The system is an active frustrated Lewis pair that undergoes cycloaddition reactions with suitable π reagents and it splits dihydrogen. At room temperature in solution the new compound is a monomer, however, in the crystal and in solution at low temperature it aggregates to a thermodynamically favoured supramolecular macrocyclic cyclooctamer.
通过用乙烯基环己烷处理，一种新的六元环状受阻膦/硼烷路易斯对从其HB(CF)加合物中释放出来。该体系是一种活性受阻路易斯对，能与合适的π试剂发生环加成反应并能使氢气分解。在室温下的溶液中，新化合物是单体，然而，在晶体中以及低温下的溶液中，它会聚集形成热力学上更稳定的超分子大环环辛聚体。
