Heterocyclic Phosphorus Ligands in Coordination Chemistry of Transition Metals

Modern stage of development of organometallic and co-ordination chemistry is characterised by the wide use of polyfunctional ligands with structurally rigid fragments. On the base of such ligands an unusual labile and polynuclear complexes -precursors of the homogeneous catalysts, have been designed. Cyclic organophosphorus compounds pertain to the ligands of such type.
