描述了一种新型杂化磷(III)氮烷/NHC体系,其中磷氮烷P2N2环为修饰这些碳烯的电子和立体特性提供了独特的机会。介绍了一种新型杂化磷酸(III)氮烷/NHC体系的简单“点击”合成方法。磷烷P2N2环单元的存在,P原子位于NCN片段的两侧,并且这个环垂直于NHC的结合位点,为修饰这些碳烯的电子和空间特征提供了独特的机会。
A new type of hybrid phosph(III)azane/NHC system is described in which a phosphazane P2N2 ring provides unique opportunities for modifying the electronic and steric character of these carbenes. A simple, “click” synthetic approach to a new type of hybrid phosph(III)azane/NHC system is described. The presence of the phosphazane P2N2 ring unit, with P atoms flanking the NCN fragment and with this ring perpendicular to the binding site of the NHC, provides unique opportunities for modifying the electronic and steric character of these carbenes.
