Copper-catalyzed N,N-diarylation and N-arylation of unprotected 8-aminoquinoline derivatives with aryl halides have been described for the formation of C–N bonds. This protocol provides an efficient approach to synthesize a series of arylamines with tolerance to a wide range of functional groups for formation of key intermediates in many natural products.

Sc(CH2SiMe3)3(THF)2 to afford the well-defined complexes (L1−5)Sc(CH2SiMe3)2(THF) (1−5), which were fully characterized by NMR spectral and X-ray diffraction analyses. Complexes 1−3 combined with organoborates to establish binary systems that exhibited high activity for the polymerization of styrene, while 4 was less active and 5 was almost inert. The cationic complex [L1Sc(CH2SiMe3)(DME)2][B(C6F5)4] (6) was
