To expand the utility of bis(terpyridine) metal connectivity, the selective symmetrical and unsymmetrical 4,4‘ ‘-functionalization (−CN, −Me, −CO2Me) of 4‘-(4-bromophenyl)-2,2‘:6‘,2‘ ‘-terpyridines was achieved using the Kröhnke synthesis. The final substituted 2,2‘:6‘,2‘ ‘-terpyridines along with their corresponding intermediates, 4a−c, were recrystallized and characterized by 1H NMR and 13C NMR as
为了扩大双(吡啶)金属连接的效用,对4'-(4-溴苯基)-2,2'进行选择性对称和不对称的4,4''-官能化(-CN,-Me,-CO 2 Me)使用Kröhnke合成法获得了:6',2''-叔吡啶。将最终取代的2,2':6',2''-吡啶及其相应的中间体4a - c进行重结晶,并通过1 H NMR和13 C NMR以及X射线晶体学进行表征;还进行了COZY相关性以允许确定的质子分配。
