Abstract
Tris(chelate)2(diene)ruthenium(II) complexes have been synthesized. All three possible diastereoisomers of Ru(bzac)2(cod) (where cod = 1,5-cyclooctadiene and bzac = benzoylacetonato) have been isolated and diastereoisomerization processes were observed at elevated temperature. The energy barriers were found to be in the range of 35-36 kcal/mol. The DNMR behaviour of Ru(S2CNMe2)2(cod) and Ru(S2PMe2)2(L) complexes is also discussed. We synthesized a new Ru(N-isopropylsalicylaldiminato)2(cod) tris-chelate which was found to clathrate some solvents.File in questo prodotto:
