A Simple Route to Univalent Gallium Salts of Weakly Coordinating Anions

Pyramidal [Ga(PPh3)3]+ (see picture) is the first structurally characterized homoleptic gallium–phosphine complex. The synthesis of this ion was aided by the development of a facile route to gallium(I) salts with weakly coordinating anions (WCAs). These salts are an outstanding source of gallium in the oxidation state +1 for the generation of previously unknown low-valent gallium compounds.
