Structural characterization of the tautomeric forms of the zwitterions proposed in the phosphine catalyzed transformations of electron-deficient allenes by utilizing a cyclodiphosphazane with a P-NH-t-Bu group and Ph 2 P(NH-t-Bu) is described. Spontaneous resolution of the products (R and S enantiom
