The superbasic tetraphosphazene is a thieving magpie on the hunt for the shiny proton. Phenols are readily deprotonated and the respective non‐coordinated anions are formed in the presence of weakly Lewis‐acidic phosphazenium counterions. Strongly nucleophilic non‐coordinated phenolates excel as reducing agents for the generation of radical anion salts and for the activation of SF 6 . Their high Lewis‐basicity is accompanied by a pronounced tendency for hydrogen bonding, which is perceptible in their chemical behavior. More information can be found in the Full Paper by B. Hoge et al. on page 6460.
