Synthesis and structure of phosphonium‐DMAP adduct 18 and estimated Lewis acidity for 19–23. Ellipsoids are set at 50 % probability; solvent molecules were removed for clarity. [27] Estimated Lewis acidity for 19–23 by the Gutmann–Beckett method and computed fluoride and hydride ion affinities (kJ mol−1) at the PW6B95‐D3(BJ)/def2‐QZVPP//B3LYP‐D3(BJ)/def2‐TZVP level of theory. Values for 21–23 obtained from reference [20d].
