1999organo-phosphorus compounds, nonmetal heterocycles organo-phosphorus compounds, nonmetal heterocycles S 0087 -191New Types of Phosphorus-Containing Crown Ethers.-The first synthesis of phosphorus-containing crown ethers with regularly alternating arylene and phosphorus acid residues such as (V) and (VI) using a molecular assemblage strategy is described. Structures and chemical properties of these compounds are studied and rhodium complexes of these macrocycles are prepared. -(NIFANTIEV, EDWARD E.; RASADKINA, ELENA N.; YANKOVICH, INNA V.; VASYANINA, LARISA K.; BELSKII, VITALY K.; STASH, ADAM I.; Heteroat.
