Cr. Rice et al., Pyridyl-thiazoles as a new class of ligand for metallosupramolecular chemistry: formation of double and triple helicates with Cu(II), CHEM COMMUN, (16), 2000, pp. 1529-1530
Reaction of either 1,10-phenanthroline-2-thioamide or pyridine-2-thioamide
with 1,4-dibromobutane-2,3-dione affords the novel thiazole-containing poly
dentate ligands L-1 and L-2, respectively; these ligands form dinuclear dou
ble and triple helicate architectures, respectively, with Cu2+.
