Abstract

Phosphoranes P(OC6H4NR)2(OC6H4NHR) [R = Me (2a), Ph (2b), C6F5 (2c)] were synthesized by treating PCl5 with the respective 2-aminophenol derivative (1a–c, 3.1 equiv.). In one instance, an intermediate species, P(OC6H4NR)2Cl [R = Me (3a)], was isolated and structurally characterized. Deprotonation of the amine moieties (–N[H with combining low line]R) in phosphoranes 2a and 2b with a strong alkali–metal base (e.g. n-BuLi) in the presence of a strong-donor solvent (e.g. THF) afforded salts composed of the hexacoordinate P(V)-anions [P(OC6H4NR)3] (R = Me, [4a]; Ph, [4b]). Employing precursor 2a, the salt Li(THF)3fac-[4a] was isolated. The X-ray crystal of each enantiomer of [4a] was determined and, to our knowledge, represents the first structurally characterized example of a salt containing a hexacoordinate P(V)N3O3 anion featuring P(V)–N bonds.
