Metal
complexes of linear bilateral extended 2,2′:6′,2″-terpyridine
[2,6-bis(2-substituted furo[2,3-c]pyridin-5-yl)pyridine]
are topological tridentate analogues of 5,5′-functionalized
2,2′-bipyridine. The present methodology provides access to
linear bilateral extended 2,2′:6′,2″-terpyridineruthenium(II)
complexes starting from 5,5″-bis(methoxymethoxy)-4,4″-bis(substituted
ethynyl)-2,2′:6′,2″-terpyridines via one-pot
cleavage of the methoxymethyl (MOM) protecting group, cycloisomerization,
and metal complexation in the presence of Ru(DMSO)4Cl2. In this reaction, ruthenium(II) likely plays a triple role,
acting as a Lewis acid to cleave the MOM ether, a catalyst facilitating
5-endo-dig cyclization, and a coordination metal center, being an
integral part of the final product.
