Cluster Chemistry

摘要: The syntheses of over sixty known and new derivatives Ru3(CO)12 H4Ru4(CO)12 by substitution reactions initiated sodium diphenylketyl are described. range ligands studied includes isocyanides, tertiary phosphines phosphites, arsines SbPh3. characterised high degrees specificity conversion: under mild conditions up to four can be introduced. Comparisons with the corresponding thermally induced made in several cases. provide routes mixed ligand cluster carbonyls, although account relative Lewis base strengths may have taken. Possible mechanisms these discussed briefly, as IR ν (CO) spectra Ru3 (CO)12-nLn complexes.
