| Abstract: | Efforts to prepare an elusive donor-free phosphenium ion, R2P]+, led us to synthesize functionalized fluorophosphonium cations of the type R2P(F)X]+ (X=SiEt3, H, F), which were obtained from the related neutral fluorophosphines R2PF and R2PF3 upon protonation and reaction with solvated Et3Si]+ ions (R=2,6-Mes2C6H3). The hypothetical reductive elimination of R2P(F)SiEt3]+ and R2P(F)H]+ affording R2P]+, Et3SiF and HF, respectively, was calculated to be endothermic by 40.1 and 190.6 kJ mol−1. |
