General R 0010Nitrogen-Directed ortho-Arylation and -Heteroarylation of Aromatic Rings Catalyzed by Ruthenium Complexes. -The Ru-catalyzed ortho-arylation reaction is successfully extended to the direct coupling of arenes (I) and (V) with hetaryl bromides (II). Microwave heating can significantly reduce the reaction time [cf. (VIII)]. -(OI*, S.; FUNAYAMA, R.; HATTORI, T.; INOUE, Y.; Tetrahedron 64 (2008) 26, 6051-6059; Dep. Biomol. Eng., Grad. Sch.
