Taming the Cationic Beast: Novel Developments in the Synthesis and Application of Weakly Coordinating Anions

“…However,t here are myriads of further applications that are much easier to realize using the advice given in this Review.Goa head and try!

The role of solvent‐ligated metal(II) complexes incorporating (fluoroalkoxy)aluminates as weakly coordinating anions in isobutylene polymerization

“…The synthesis and characterization of the nitrile‐ligated copper(II) and zinc(II) complexes were already described and published by Li et al39, 49 Several publications regarding the synthesis route, intermediates used, and the applications of the copper(II) and zinc(II) complexes were also described in the literature 37–39…”

“…Recently, Kühn and coworkers37–39 reported on the synthesis of the nitrile‐ligated silver(I) complex [Ag(NCR′) 4 ][Al(OC(CF 3 ) 3 ) 4 ] and the copper(II) complex [Cu(NCR′) 6 ][Al(OC(CF 3 ) 2 R) 4 ] 2 (R′ = CH 3 and Ph; R = CF 3 , Ph, and PhCH 3 ) with perfluoroalkoxy aluminates or [aluminates‐WCAs] as the corresponding counteranions 37–39. The very good activity demonstrated particularly by the copper(II) complexes for olefin aziridination is an indication for the advantages of perfluoroalkoxy aluminate WCAs when compared with other classical WCAs as counteranions.…”

Synthesis, Characterization and Application of Nitrile‐Ligated Zinc(II) Complexes Incorporating (Fluoroalkoxy)aluminates

“…Very recently, we reported on the synthesis of nitrile‐ligated silver(I) and copper(II) complexes with (per/polyfluoroalkoxy)aluminates as counteranions: [Ag(NCCH 3 ) 4 ][Al(OC(CF 3 ) 3 ) 4 ]9 and [Cu(NCR′) 6 ][Al(OC(CF 3 ) 2 R) 4 ] 2 (R′ = CH 3 , Ph; R = CF 3 , Ph, PhCH 3 ) 10. The very good activities of copper(II) complexes for olefin aziridination10,11 demonstrated the superiority of (per/polyfluoroalkoxy)aluminates (Figure 1) in comparison to other classical WCAs as counteranions for this type of complexes. First reported in 2001,12 [Al(OC(CF 3 ) 3 ) 4 ] – has been applied as counteranion for [H(OEt 2 ) 2 ] +[13] and [AlCp 2 ] +[14] for thepolymerization of isobutylene.…”
