Readily available P-^tBu substituted Li/Cl phosphinidenoid complexes react with carbonyl compounds to furnish sterically almost unhindered oxaphosphirane complexes that reveal new and surprisingly facile intra- and intermolecular ring expansion reactions. 1,3,2-Dioxaphosphole complex formation is explained by DFT calculations through diastereoselective carbonyl group-induced ring cleavage of an oxaphosphirane intermediate.

对磷的空间保护作用减弱对氧杂磷杂环丙烷配合物的稳定性和反应性的影响†

现成的P - ^t Bu取代的Li / Cl膦基类固醇络合物与羰基化合物反应，可提供空间几乎不受阻碍的氧杂磷杂环戊烷络合物，从而揭示了新的且出乎意料的分子内和分子间环膨胀反应。通过非对映选择性羰基基团诱导的氧杂膦烷中间体的环裂解，通过DFT计算来解释1,3,2-二氧杂磷杂环戊烯络合物的形成。
