• The synthetic pathway to the functional phosphonium 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]+ and the corresponding anion, crystal structures of the compounds [Cy3PCHCl2]Cl·2CHCl3 (3a) and [Cy3PCHCl2]3[H3O][H5O2]Cl5·C6D6 (3b) could be obtained and evaluated. The functional phosphonium ion [Cy3PCHCl2]+ could be synthesized, which is able to form hydrogen bonds to the corresponding anion. Through these interactions, the salts [Cy3PCHCl2]Cl·2CHCl3 and [Cy3PCHCl2]3[H3O][H5O2]Cl5·C6D6 could be stabilized. Also, the mechanism for the formation of cation [Cy3PCHCl2]+ has been investigated.
