PR 3 , also known as carbodiphosphoranes, are very reactive compounds having numerous unusual and promising properties. The first representatives of this class of divalent carbon(0) compounds have already been synthesized over 50 years ago, but aspects of their chemistry and properties remain ambiguous. Herein, we report on specific characteristics of a simple carbodiphosphorane, hexaphenylcarbodiphosphorane
摘要R 3 PC PR 3类型的双氰化物,也称为碳二膦酸酯,是具有许多不同寻常和有前途性能的非常活泼的化合物。这类二价碳(0)化合物的首批代表已于50年前合成,但其化学和性质方面仍不明确。本文中,我们基于1 H,13 C和31 P NMR研究报告了一种简单的碳二膦烷,六苯基碳二膦烷Ph 3 PC PPh 3的具体特征。将中心sp杂化碳原子的化学位移和1 J CP耦合特性与其他sp杂化碳进行了比较。我们的光谱发现得到了模拟的支持,与实验确定的值非常吻合。
