The isolation of binary As–N and ternary As–N–P cage compounds consisting exclusively of group 15 elements was achieved by exploiting the reactivity of diarsadiazanediyl. This arsenic centered biradical is capable of activating and/or quenching small molecules bearing double bonds such as diazenes, Ph–N=N–Ph, or in situ generated labile diphosphenes, e.g. Ph–P=P–Ph, leading to the formation of hexapnicta‐[2
通过利用diarsadiazanediyl的反应性来分离仅由15组元素组成的二元As-N和三元As-N-P笼型化合物。这种以
砷为中心的双自由基能够激活和/或淬灭带有双键的小分子,例如二氮杂苯,Ph–N = N–Ph或原位生成的不稳定
二膦,例如Ph–P = P–Ph,从而导致形成六碳环[2.1.1]双
环己烷。
