Bis(dimethyl sulfoxide)bis(flavonato)ruthenium(II) complexes, RuL2(DMSO)2, were synthesized by the reaction of dichlorotetrakis(dimethyl sulfoxide)ruthenium(II) with the sodium salts of 5-hydroxyflavone, 5-hydroxy-4′-methoxyflavone and 5-hydroxy-3

The new macrocycle L containing two bipyrazole subunits gives with Ru(DMSO)4Cl2 a stable trans complex in which the nature of the axial ligands has been established from 1H and 13C NMR, IR and UV experiments; the structure of the complexes obtained a

The synthesis of a biheterocyclic compound containing two pyrazolone sub-units, precursor of a new macrocyclic family, is described. It is shown that it is necessary to protect first the pyrazol-5-one oxygen site before condensing it with a bifunctio

Ten new tetraheterocyclic macrocyclic ligands 2-4 in the porphyrinogen series were prepared. The rigid dipyrazole ditriazole macrocycles 3 extract Na + selectively, whereas the more flexible dipyrazole monotriazole monopyridine macrocycles 2 have the

Reaction of cis-RuCl2(DMSO)4 with the potassium salts of 2′-hydroxychalcones L leads to the stable complexes RuL2(DMSO)2. For each ligand L three isomers of each bis(dimethyl sulfoxide)bis(chalconato)ruthenium(II) complex were found; in two of them
