摘要

New carboxy-terpyridines selectively functionalized at the 4-, 4′-and 4 ″-positions were prepared in a three-step procedure with good yields using the Kröhnke reaction followed by saponification. Their complexation with ruthenium led to symmetric and unsymmetric terpyridinyl zwitterionic complexes.
