A small variation in the vanadium reagent leads to a completely different product: The cyclooligomerization of phosphaalkynes 2 with t BuN=VCl 3 ⋅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.
