Main group element-mediated phosphaalkyne by combined insertion and oligomerization reactions.

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.
