Twice frustrated: The unusual electronic distribution around the central carbon(0) atom in carbodiphosphoranes makes this center so basic that, even after a first alkylation step, it is still able to act as a cationic Lewis base in the framework of frustrated Lewis pair chemistry.
两次失意:碳二膦酸酯中中心碳(0)原子周围不寻常的电子分布使该中心变得如此碱性,即使在第一步烷基化步骤后,它仍然能够在沮丧的路易斯对化学结构中充当阳离子路易斯碱。
