Reaction of π-coordinated Ligands

Carbide complexes as π-acceptor ligands

The p-accepting character of a terminal carbide complex acting as a ligand is demonstrated experimentally and corroborates earlier theoretical predictions. As a result, coordination of a terminal ruthenium carbide complex to electron-rich metal centres is shown to provide a facile and versatile route to carbidebridged heterometallic complexes. Synthesis, reactivity, spectroscopic and structural...

π Ligands in Alkaline Earth Complexes

Se p 19 99 Production of the π − , π 0 in the reaction d ( e , pp ) e ′ π − π 0

Recently, the differential yield and target asymmetry of the reaction d(e, pp)eπ on the tensor polarized deuterium target have been presented in [1, 2], where the experimental procedure and basic assumption were described. A precise treatment of this reaction needs to investigate the reaction channels with an additional neutral pion production as a background to the leading reaction of a single...

Inversion of axial chirality in coordinated bis-β-diketonato ligands.

Mononuclear and dinuclear ruthenium(III) complexes with bis-β-diketonato ligands (denoted by [Ru(acac)(2)(L-LH)] and [Ru(acac)(2)(L-L)Ru(acac)(2)], respectively) were synthesized, where acac, L-LH(-) and L-L(2-) denote acetylacetonato, monoprotonated and unprotonated bis-β-diketonato ligands, respectively. The following three ligands were used as the bis-β-diketonato ligand (L-L(2-)): 1,2-diace...

Unique Reactivity Characteristics of Mo-coordinated !&- and S$- Ligands

The synthesis of the new dithiolene complexes, [{(MeOOC),C,S2}2Mo(2-S)]; and [OMo(S2C2(COOMe)2)2]2, is reported. These complexes are obtained by the reaction of dicarbomethoxyacetylene (DMA) with either [(S~)MO(S)(~~-S)~MO(S)(S~)]~or [(CS~)MO(S)(~~-S)~MO(S)(CS~)]~and [OMO(S~)~]~-, respectively. The reaction of [(S4)Mo(0)(~2-S)2Mo(O)(S2)]2with DMA results in the new dithiolene complex [{(MeOOC)2...
