Oxidative coupling of 6-(pyridin-2-yl)pyridine-2(1H)-thione yields 1,2-bis(2,2′-bipyridin-6-yl)disulfide (4), which can act as a bis(chelate) to a single zinc(ii) centre. The effects on the solid-state structure of introducing a methyl substituent into each 6-position of 4 have been examined. Ligand 4 functions as a bridging ligand in [Cu2(-4)(-6)]4+ in which ligand 6 is 1,2-bis(2,2′:6′,2″-terpyridin-4′- yl)disulfide; [Cu2(-4)(-6)]4+ self-assembles from the components according to the preference shown by copper(ii) for a five-coordinate {Cu(bpy)(tpy)} environment. Reaction of 4 with [Cu(NCMe)4][PF 6] leads to a product, tentatively formulated as {[Cu(4)][PF 6]}n, which, in air, undergoes oxidation of both copper and ligand to yield [Cu(5)2] (H5 ≤ 2,2′-bipyridine-6- sulfonic acid), the solid state structure of which is presented.

This study focusses on a new concept for oligosaccharide synthesis based on 4-(pyridin-2-yl)thiazol-2-yl thioglycosides that can either act as effective glycosyl donors or can be deactivated by stable bidentate complexation with palladium(ii) bromide. The Royal Society of Chemistry.
Synthetic strategies for preparing BEDT-TTF derivatives functionalised with metal ion binding groups

, p. 1790 - 1800 (2008/02/05)
The syntheses of BEDT-TTF (ET) derivatives with potential metal ion binding pyridyl, bipyridyl and terpyridyl groups is achieved either by stepwise construction of the organosulfur core or via reactions of hydroxymethyl-ET for which a cheap and efficient
A convenient set of bidentate pyridine ligands for combinatorial synthesis
Wang, Fen,Schwabacher, Alan W.
, p. 4779 - 4782 (2007/10/03)
Synthesis is reported of five pyridine-containing bidentate ligands bearing nucleophilic groups at different positions. Their efficient solid- phase alkylation was demonstrated in the synthesis of a small library. These ligands are attractive building blocks for the construction of libraries of metal-binding compounds for various purposes.
