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, tBuOO, SCN, OAc, SAr), many of them for the first time. The availability of these complexes allowed us to evaluate the trans-influence order of ligand in Cu(III) complexes: Bn > CF3– > C6F5– > N3– > py
综合摘要明确定义的氟化铜(III)配合物 Me4N+[Cu(CF3)3(F)]- 1 的发明使我们能够获得多种功能化的铜(III)配合物 [Me4N]+[Cu(X)(CF3)3]- (X = C6F5, C6F5C≡C, CN, Cl, N3, tBuOO, SCN, OAc, SAr),其中许多配合物还是首次发现。有了这些配合物,我们就可以评估 Cu(III)配合物中配体的反式影响顺序:Bn > CF3- > C6F5- > N3- > py ~ CH3- ~ C6F5C≡C > NO2PhO- ~ tBuOO- ~ CH3COO- > F-。
