The metal-initiated cyclooligomerization of phospha-alkynes and its consequences [1]

Article abstract of DOI:10.1080/10426509908546231

1,3-Diphosphacyclobutadienes 4 are almost certainly intermediates in the conversion by hexachloroethane of phosphaalkyne dimer complexes 3 to the tetraphosphacubanes 5. We now describe trapping reactions of 4, generated in the same way, wilh phosphaalkyne 1 (→9), ynamines 10 (→13), and electron-poor alkynes 11 (→14). The cyclooligomerization of 1 initiated by t-Bu-N=VCl₃·DME (15) leads to the azatetraphosphaquadricyclanes 20 while the reaction with the stronger Lewis acid t-Bu-N=VCl₃ (21) furnishes the 1,3,5-triphosphabenzenes 23 in high selectivity.
