The invention of a well-defined Cu(III) fluoride complex Me4N+[Cu(CF3)3(F)]- 1 enabled to access a versatile of functionalized Cu(III) complexes [Me4N]+[Cu(X)(CF3)3]- (X = C6F5, C6F5C≡C, CN, Cl, N3, t BuOO, SCN, OAc, SAr), many of them for the first time. The availability of these complexes allowed us to evaluate the the trans-influence order of ligand in Cu(III) complexes: Bn > CF3 – > C6F5 – > N3 – > py ~ CH3 – ~ C6F5C≡C > NO2PhO– ~ t BuOO– ~ CH3COO– > F–.
