“…An analogous NH-substituted derivative was obtained in low yield via transamination of o -phenylenediamine with ethoxybis(diethylamino)phosphine [28] , and condensation of o -phenylenediamine with excess tris(diethylamino)phosphine furnished a 1,3-bis(phosphino)-substituted heterocycle [29] . Intermediates with one or two NH functions were detectable by spectroscopy but could not be isolated in pure form under these conditions.…”

This chapter gives a survey on five-and six-membered phosphorusnitrogen heterocyclic compounds whose rings combine a phosphazene (>N-P = N-) or phosphazane (>N-P(X)-N<) unit with an unsaturated C 2 or C 3 building block. Representatives contain structurally diverse species like aromatic 1,3,2-diazaphosphinines and (benzo)-1,3,2-diazaphospholes, cationic counterparts of subvalent main-group carbene analogues like 1,3,2-diazaphospholenium ions and phosphenium-diketiminates, and neutral heterocycles like 1,3,2-diazaphospholenes featuring unusual structures and reactivities. The exploration of these species developed rapidly in the last two decades in the wake of cutting edge research on multiple bonding and low coordination in the chemistry of heavier main-group elements, and the discovery of stable carbenes. This review summarizes the elaboration of synthetic approaches for different types of N -heterocyclic phosphine derivatives, discusses their characterization by physical and computational methods which furnished a thorough understanding of structure and bonding, and finally highlights accomplishments in the exploration of the chemical properties at the border of classical organic heterocyclic chemistry and molecular inorganic chemistry.
