Abstract
A number of new spiro-ansa spermidine derivative cyclotriphosphazenes (2-10) is synthesized in order to provide insight into the reaction mechanism for nucleophilic substitution. The structures of the compounds were determined by elemental analysis, mass (MS), (1)H, (19)F (for 9) and (31)P NMR spectroscopies. Compounds (2-8) and 9, 10 can be formed by a proton abstraction-chloride elimination and both the S(N)(1) and S(N)(2) reaction mechanisms, respectively.
