Abstract

High-field two-dimensional ³¹P NMR spectroscopy (³¹P-³¹P COSY) has been used to study the regio- and stereoselectivity in the nucleophilic substitution reactions of the (triphenylphosphazenyl)cyclotriphosphazene, N₃P₃Cl₅(N=PPh₃) with trifluoroethoxide or aryloxides and to identify isomeric λ⁵-bicyclic phosphazenes. The structures and conformations of λ³-cyclotriphosphazanes and their reactivity towards transition metal derivatives and oxidation and oxidative addition reactions have been investigated.
