Application of quinoxaline based diimidazolium salt in palladium catalyzed cross-coupling reactions / created by Mujahuddin M. Siddiqui, Mohammed Waheed, Sajad A. Bhat and Maravanji S. Balakrishna - Journal of chemical sciences Volume 127, number 5, .
The reaction of 2,3-bis(bromomethyl)quinoxaline with imidazole afforded the quinoxaline bridged diimidazolium salt (1) in good yield. Diimidazolium salt (1) in conjunction with Pd(OAc)2 was employed as a catalyst for C–C cross-coupling reactions. The diimidazolium salt was found to be efficient in catalyzing Suzuki-Miyaura cross-coupling reaction in ethanol under ambient conditions. Moderate to good selectivity of the trans product was observed in the Heck cross-coupling reaction. The molecular structure of 1 was confirmed by single crystal X-ray diffraction study.
