Synthesis of mono-, bis- and tris-tridentate ligands based on 5′-substituted-2,2′-bipyridine-6-carboxylic acid
Charbonnière, Loc J.,Weibel, Nicolas,Ziessel, Raymond F.
, p. 659 - 662 (2001)
The synthesis of 5′-methyl-2,2′-bipyridine-6-carboxylic acid is described starting from the pivotal 5′-methyl-6-bromo-2,2′-bipyridine building block. Functionalisation of the latest at the 5′-methyl position gives access to the 5′-bromomethyl, 5′-hydroxymethyl and 5′-aminomethyl derivatives. Upon nucleophilic substitution, the hydroxy and amino derivatives react with the 5′-bromomethyl compound to give quasi-linear and podand type intermediates. Thanks to a carboalkoxylation reaction at the 6-bromo position of the different intermediates, followed by a saponification reaction, mono-, bis- and tris-tridentate ligands are obtained, which are particularly well suited for the complexation of lanthanide(III) cations.

Synthesis of a novel ditopic ligand incorporating directly bonded 1,10-phenanthroline and 2,2′:6′,2″-terpyridine units
Gavi?a, Pablo,Tatay, Sergio
, p. 3471 - 3473 (2007/10/03)
The synthesis of a rigid ditopic ligand incorporating a 1,10-phenanthroline directly connected through its 3-position to the 5-position of a 2,2′:6′,2″-terpyridine is described. The synthesis is based on a series of palladium(0)-catalyzed cross-coupling reactions (Stille and Suzuki couplings) starting from 1,10-phenanthroline and bromo-substituted pyridines.
Synthesis of flexible polydendate ligands bearing 5′-substituted-6-carboxylic-2,2′-bipyridine subunits
Charbonnière, Lo?c J.,Weibel, Nicolas,Ziessel, Raymond F.
, p. 1101 - 1109 (2007/10/03)
The synthetic scope of asymmetric 5′,6-disubstituted-2,2′-bipyridines in the preparation of flexible multitopic ligands has been investigated. The preparation of the pivotal 6-bromo-5′-bromomethyl-2,2′-bipyridine building block involved a Kr?hnke protocol
