two phosphorus atoms, one of which is in the trivalent three-coordinate state, undergo [1+4]-cycloaddition with 3,6-di-tert-butylbenzo-1,2-quinone under mild conditions to form phosphoranes of different nature. Diphosphorus-containing compounds, in which the phosphorus atoms are in different coordination states, were obtained. The presence of halophosphorane moieties in the starting compounds does
含有两个磷原子的连苯三酚和羟基氢醌的磷酸化衍生物,其中一个处于三价三配位状态,在温和条件下与 3,6-二叔丁基苯并-1,2-醌发生 [1+4]-环加成反应形成不同性质的正膦。得到含二磷的化合物,其中磷原子处于不同的配位状态。起始化合物中卤代正膦部分的存在不会阻止反应在温和条件下通过环加成定量进行。
