Gallium(I) Complexes Similar to a Japanese bento box, gallium(I) chemistry offers a wide range of “different tastes” regarding fundamental and applied science. In their Full Paper on page 157 ff., I. Krossing et al. describe the ansa ‐arene complexes [Ga(PhC 2 H 4 Ph) 2 ] + and [(C 6 H 5 F)Ga( μ ‐1,3‐Ph 2 C 6 H 4 ) 2 Ga(C 6 H 5 F)] 2+ , featuring the weakly coordinating [Al(OC(CF 3 ) 3 ) 4 ] − anion, that not only deliver interesting insights into the bonding nature of univalent gallium, but also are highly efficient catalysts for the polymerization of isobutylene. WCA=weakly‐coordinating anions. PIB=polyisobutylene.
