Abstract

The aminolysis of the hexachlorocyclotriphosphazene, N3P3Cl6 1, by the oxodiamines H2N-(CH2)3-O(CH2)2-O-(CH2)3 NH2 2 and H2N-(CH2)3-O-(CH2)6-O-(CH2)3-NH2 3 occurs immediately and regiospecifically in dry media leading to the corresponding spiranic cryptands 4 and 5, respectively. This process is an actual improvement (time, selectivity and workup) on the standard reactions.
