A convenient one-pot procedure for the preparation of 1-(diisopropylamino)phospholes has been developed. These phospholes have been used in a multistep procedure for synthesizing two new2,2′-biphosphole disulfide compounds. The structures and stereochemistry of these compounds have been studied by X-ray diffraction analysis and by molecular modeling. The 1-(diisopropylamino) group, used as a bulky
已开发出一种方便的一锅法制备 1-(二异丙基氨基) 磷。这些磷已用于合成两种新的 2,2'-双磷二硫化物的多步程序。这些化合物的结构和立体化学已经通过 X 射线衍射分析和分子建模进行了研究。1-(二异丙基氨基)基团作为磷原子上的大取代基与环上的苯基结合使用,被证明是稳定 2,2'-双磷骨架轴向手性的重要因素。
