Base assisted C-C coupling between carbonyl and polypyridyl ligands in a Ru-NADH-type carbonyl complex
A reaction of a ruthenium(II) NAD-type complex, [Ru(tpy)(pbn)(Cl)](+) (tpy = 2,2′:6′,2 ”-terpyridine; pbn = 2-(pyridin-2-yl) benzo[b][1,5] naphthyridine), with pressurized CO (2 MPa) at 150 degrees C in H2O selectively produced a two-electron reduced ruthenium(II)-NADH-type carbonyl complex, [Ru(tpy)(pbnHH)(CO)](2+) (pbnHH = 2-(pyridin-2-yl)-5,10-dihydrobenzo[b][1,5] naphthyridine), rather than the oxidized [Ru(tpy) (pbn)(CO)](2+) complex. Indeed, [Ru(tpy)(pbnHH)(CO)](2+) was quantitatively oxidized to [Ru(tpy)(pbn) (CO)](2+) upon treatment with one equiv. of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ). The reactivity of [Ru(tpy)(pbnHH)(CO)](2+) with various bases was studied herein. Treatment of [Ru(tpy)(pbnHH) (CO)](2+) with a suitable organic base, 1,5-diazabicyclo[4.3.0] non-5-ene (DBN), resulted in the formation of a new five-membered Ru-CO-bridge metallacycle quantitatively in acetonitrile under air at room temperature. A probable mechanism was proposed for this reaction based on UV-vis, NMR, and EPR spectral studies and other experimental data. Furthermore, a reaction of the five membered Ru-CO-bridge metallacycle with NH4PF6 in CH3CN : H2O (1 : 1) under air smoothly produced another new six-membered Ru-OCO-bridge complex. A mechanism for the formation of a Ru-OCO-bridge complex was also proposed here on the basis of H2O18 experiments, DDQ treatment and other experimental data. These newly synthesized complexes appended with NAD-type ligands may have potential use as renewable hydride sources for organic reductions.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2835-95-2 is helpful to your research. Category: naphthyridines.
