Towards to the trans-bromination of 2-styrylpyridine with a palladacycle intermediary and structure analysis for trans-1,2-dibromo-2-styrylpyridine
(ELSEVIER SCIENCE BV, 2011)
The simple halogenation of alkynes in conventional organic reactions gives a blend of cis and trans isomers. It is proposed then, a synthesis of stereospecific halogenation of alkynes in trans position, using palladacycle ...
Cis- Trans Interconversion in Ruthenium(II) Bipyridine Complexes
(American Chemical Society, 2019-09)
Most studies of ruthenium polypyridine complexes are devoted to their cis isomers. The fact that cis isomers are thermally more stable and thus easier to synthesize has prevented researchers from investigating the properties ...
Optomechanical trans-to-cis and cis-to-trans isomerization and unusual photophysical behavior of fac-[Re(CO)(3)(phen)(CNstpy)](+)
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Unusual high photoassisted quantum yields for cis-to-trans (phi(254) (nm) = 0.27 +/- 0.05) isomerization of CNstpy coordinated to fac-[Re(CO)(3)(phen)(CNstpy)](+) were determined along with trans-to-cis ones (phi(313) (nm)= ...
Cis–trans isomerization in the syntheses of ruthenium cyclam complexes with nitric oxide
(2012)
The cis to trans isomerizations during the syntheses of trans-[Ru(NO)(OH)(cyclam)](PF6)2, from cis-[RuCl2(cyclam)]Cl, and [Ru(NO)Cl(cyclam)] (PF6)2, from cis-[RuCl2(dmso)4], are reported. The novel trans-[Ru(NO)(OH)(cyclam)](PF6)2 ...
Phochemical behavior of trans-[Ru(NH3)4P(OEt)3L]2+ complex ions (L = P(OEt)3, CO, H2O)
(1992-12-01)
trans-[Ru(NH3)4P(OEt)3H2O] 2+, trans-[Ru(NH3)4(P(OEt)3)]2+, and trans-[Ru(NH3)4P(OEt)3CO]2+ were photolyzed with light of 313 nm on the lowest energy ligand field excited state. Photoaquation of the thermally substitution ...
Phochemical behavior of trans-[Ru(NH3)4P(OEt)3L]2+ complex ions (L = P(OEt)3, CO, H2O)
(1992-12-01)
trans-[Ru(NH3)4P(OEt)3H2O] 2+, trans-[Ru(NH3)4(P(OEt)3)]2+, and trans-[Ru(NH3)4P(OEt)3CO]2+ were photolyzed with light of 313 nm on the lowest energy ligand field excited state. Photoaquation of the thermally substitution ...
(1)H NMR spectroscopy as a tool to determine accurate photoisomerization quantum yields of stilbene-like ligands coordinated to rhenium(I) polypyridyl complexes
(ELSEVIER SCIENCE SA, 2010)
In this work, the use of proton nuclear magnetic resonance, (1)H NMR, was fully described as a powerful tool to follow a photoreaction and to determine accurate quantum yields, so called true quantum yields (Phi(true)), ...
