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

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

13C NMR spectroscopic data are reported for the s-triazolo-as-triazinones of five isomeric series. Comparison of their 13C chemical shifts and CH coupling constants allows the determination of the type of ring junction of the two heterocycles, as wel

From a 1H nmr study it has been possible to show that the eight-membered ring of the N,N′-disubstituted 3,4-dihydro-1,6-benzodiazocine-2,5-diones has a boat conformation, the interconversion barrier of which is slightly over 100 kJ/mol.

The effects of substitution, lanthanide-shift reagents, solvent changes, and tautomerism were investigated on the ^(13)C chemical shifts of pyrrole, pyrazole, imidazole, s- and v-triazole, and tetrazole. It was concluded that ^(13)C chemical shifts a
