Abstract
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 containing oxygenation product.
摘要
分子内 1-PMes2/8-B(C6F5)2 取代联苯受阻路易斯对 4 表现出一些类似于分子间 FLP 体系的行为。它与一系列 1-炔烃发生反式 1,2-加成，得到相应的杂环八元 E-烯烃 8。P/B FLP 4 还与三重态氧气反应，生成含有[P]-O-B的氧化产物。
