Regioselective Suzuki—Miyaura Cross-Coupling Reactions of 2,6-Dichloro-quinoxaline. — The title reaction proceeds selectiveley at the 2-chloro substituent of substrate (I). Conditions B) for a second cross-coupling afford disubstituted products with 2 different aryl substituents. The latter conditions are also suitable for direct bis-cross-coupling. — (ALI, I.; SIYO, B.; AL-SOUD, Y.; VILLINGER, A.; LANGER*, P.; Synthesis 2012, 11, 1637-1646, http://dx.doi.org/10.1055/s-0031-1289754 ; Inst.
