摘要：

New light is thrown on reactivity of the h are often used in base-induced dehydrohalogenations, by their reaction with chloro- and dichlorophosphanes. They form chloride salts with onio- and dionio-substituted phosphanes as cations: that is , DBN and DBU behave as nucleophiles! After anion exchange with KPF6 these salts can be obtained in crystalline form. The dictation 1, for example, was characterized by X-ray diffraction. R = (cyclo-C6H11)2N. [GRAPHICS
