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。

New carboxy-terpyridines selectively functionalized at the 4-, 4'- and 4"-positions were prepared in a three-step procedure with good yields using, the Krohnke reaction followed by saponification. Their complexation with ruthenium led to symmetric and unsymmetric terpyridinyl zwitterionic complexes. (c) 2006 Elsevier Ltd. All rights reserved.
