cation [Cy3PCHCl2]+ (3) has been evaluated by using in situ 31P NMR spectroscopy and mass spectrometry. The synthesis is only successful if CCl4/CHCl3 mixtures are used. A mechanism for the varying reactivity in different solvents is given as well as a mechanism for the observed equilibrium between ions [Cy3PCHCl2]+ and [Cy3PCH2Cl]+ (12). Through the anticipated hydrogen bonding interaction between [Cy3PCHCl2]+
通过使用原位31 P NMR光谱和质谱法评估了功能性phospho阳离子[Cy 3 PCHCl 2 ] +(3)的合成途径。仅当使用CCl 4 / CHCl 3混合物时,合成才能成功。给出了在不同溶剂中变化的反应性的机理,以及观察到的离子[Cy 3 PCHCl 2 ] +和[Cy 3 PCH 2 Cl] +(12)之间平衡的机理。通过[Cy 3之间的预期氢键相互作用[Cy 3 PCHCl 2 ] Cl · 2CHCl 3(3a)和[Cy 3 PCHCl 2 ] 3 [H 3 O] [H 5 O 2 ] Cl 5 · C的PCHCl 2 ] +和相应的阴离子,晶体结构6 D 6(3b)可以得到并评估。
