Abstract
Oxidative addition of tetrachloro-ortho-benzoquinone to λ3-cyclotriphosphazanes, [EtNP(OR)]3 results in an unprecedented ring contraction–rearrangement to give diazadiphosphetidines (EtN)2[P(OR)(O2C6Cl4)][P(O2C6Cl4){N(Et)P(OR)2}](R = C6H4Br-4 or C6H3Me2-2,6), a process indicated to be thermodynamically favourable on the basis of PM3 calculations.Keywords
