Abstract This review describes reactions of 1λ3-phosphaalkynes with main group elements. The literature herein covers all known compounds by combined insertions and oligomerization reactions of 1λ3-phosphaalkynes with various halides of groups 13 and 15 that have been structurally characterized by X-ray diffraction techniques. The available 1λ3-phosphaalkynes and their unsupported phosphorus-carbon cyclo-oligomer cage compounds are included. These investigations show 1λ3-phosphaalkynes, R–C≡P, are ideal starting materials for formation of organophosphorus cage compounds, owing to their enormous potential for cycloaddition and cyclooligomerization reactions.

通过结合插入和低聚反应的主族元素介导的磷炔

摘要 本综述描述了 1λ3-磷炔与主族元素的反应。本文的文献涵盖了通过 1λ3-磷炔与各种 13 和 15 族卤化物的组合插入和低聚反应的所有已知化合物，这些卤化物已通过 X 射线衍射技术在结构上表征。包括可用的 1λ3-磷炔及其无载体的磷碳环低聚物笼状化合物。这些研究表明，1λ3-磷炔，R–C≡P，是形成有机磷笼化合物的理想起始材料，因为它们具有巨大的环加成和环低聚反应潜力。图形概要
