A small variation in the vanadium reagent leads to a completely different product: The cyclooligomerization of phosphaalkynes 2 with tBuN=VCl ⋅DME (DME=1,2-dimethoxyethane) proceeds with incorporation of the imido fragment to give the azatetraphosphaquadricyclanes 1. In contrast, with the corresponding vanadium compound containing no Lewis base this fragment is not incorporated, and the 1,3,5-triphosphabenzenes 3 are obtained.
钒试剂的微小变化会导致完全不同的产物
磷炔2与tBuN=VCl·DME（DME = 1,2 - 二甲氧基乙烷）的环齐聚反应在引入亚氨基片段的情况下进行，生成氮杂四磷四方烷1。相比之下，使用不含路易斯碱的相应钒化合物时，该片段不会被引入，而是得到1,3,5 - 三磷苯3。
