Synthesis, Structure, and Lewis Acidity of Heavy Pnictenium Cations
European Journal of Inorganic Chemistry, EarlyView.A series of donor‐coordinated and donor‐free heavy pnictenium cations were synthesized and structurally characterized. The cations are strong Lewis acids according to experimental (Gutmann–Beckett method) and computational studies (FIAs). Strained pnictanes L1PnNaph (Pn = Sb 1, Bi 2; L1 = 2,6‐(2,4,6‐i‐Pr3C6H2)2C6H3) were synthesized and protonation ...
