We have explored the use of (diethoxymethyl)benzaldehyde readily available as a starting material allowing us to end up with Terpyridinebenzaldehyde isomers. An environmentally friendly procedure was undertaken for synthesis series 4, 3 and 2-([2,2′:6′,2″-terpyridin]-4′-yl)benzaldehyde isomers (para, meta ortho position). These compounds been synthesized in one-pot conditions using ethanol aque...
