- Abstract
A cationic phosphanyl substituted plumbylene has been generated by chloride abstraction from a neutral bisplumbylene embedded into a bicyclic [3]ferrocenophane scaffold. The primary cationic bisplumbylene [Fe(C5H4PtBuPb)2Cl]+AlCl4– has been characterized by multinuclear NMR spectroscopy, mass spectrometry, and elemental analysis. It undergoes rapid chloride exchange with its neutral counterpart in solution, and adduct formation between both components has been identified via single‐crystal X‐ray diffraction. The energy balance for chloride abstraction and adduct formation has been explored for a simplified model system using DFT calculations, which was also used to assess the charge distribution within these molecules. The highly electrophilic nature of a cationic bis(phosphanylplumbylene) requires donor free solvents for chloride abstraction.
