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 Ph2P(NH-t-Bu) is described. Spontaneous resolution of the products (R and S enantiomers of the crystals) via crystallization is highlighted.
描述了通过利用具有P-NH- t - Bu基团和Ph 2 P(NH- t- Bu)的环二磷氮烷在膦催化的电子缺陷型烯的膦催化的转化中提出的两性离子的互变异构形式的结构表征。通过结晶自发地分离出产物(晶体的R和S对映异构体)。
