The new phosphinocyclotriphosphane (t-BuP)2P-P(SnMe3)2 (1) has been obtained by reaction of di-tert-butylchlorocyclotriphosphane with tris(trimethylstannyl)phosphane, and has been isolated in pure form. The yellow solid is stable below 0 °C under inert conditions. Compound 1 is a dynamic molecule, as the P atom of the [bis(trimethylstannyl)phosphino] group has a very low barrier to inversion due to
新的膦基环三膦 (t-BuP)2P-P(SnMe3)2 (1) 是通过二叔丁基氯环三膦与三(三甲基甲锡烷基)膦反应获得的,并以纯形式分离出来。在惰性条件下,黄色固体在 0 °C 以下是稳定的。化合物 1 是一个动态分子,因为 [双(三甲基甲锡基)膦基] 基团的 P 原子由于庞大且带正电的 Me3Sn 取代基而具有非常低的反转势垒。
