- Abstract
- The 1,3,2,4-diazadiphosphetidine ring 1, bearing two macrocyclic units, reacts with ethanol to form the chiral bis-macrocycle 2, including an asymmetric phosphorus center. 2 has been isolated as its chiral and racemic crystalline forms; both were structurally characterized using X-ray crystallography. The bis-macrocyclic molecule has a similar shape in the two crystal forms. A water molecule is complexed in one of the macrocylic units, inducing strong conformational changes respectively to the uncomplexed one.
