Abstract
Aminolysis of two-ring bridged-assembly cyclophosphazenes (coded as bino moieties) by long-chain diamines, H2N—(CH2)n-NH2 (n 6), leads regiospecifically to decadangling (or decapodanes or decapus) monomeric species provided it was achieved on alumina impregnated with a suitable amount of potassium hydroxide. These reactions run very fast at room temperature. Such decapodanes constitute starting materials (spherical bi-cores) for future design of cyclophosphazenic dandelion dendrimers.
