The intramolecular 1-PMes₂/8-B(C₆F₅)₂ substituted biphenylene frustrated Lewis pair 4 shows some behavior reminiscent of intermolecular FLP systems. It undergoes trans-1,2-addition to a series of 1-alkynes to give the respective heterocyclic eight-membered E-alkenes 8. The P/B FLP 4 also reacts with triplet dioxygen to yield the [P]–O–[B](OC₆F₅) containing oxygenation product.

通过将炔烃加到联苯基膦/硼烷上受阻的路易斯对上，选择性地形成杂环反式环烯烃†

分子内1-PMes ₂ / 8-B（C ₆ F ₅）₂取代的联苯阻抑的路易斯对4显示出一些行为，让人联想到分子间FLP系统。它经历反式-1,2-加成反应生成一系列1-炔烃，得到各自的杂环八元E-烯烃8。P / B FLP 4也与三重态双氧反应生成[P] –O– [ B]（OC ₆ F ₅）含氧合产物。
