Efficacy of the ferrocene appended piano-stool dipyrrinato complexes [(eta6-C6H6)RuCl(fcdpm)] (1), [(eta6 – C10H14)RuCl(fcdpm)] (2), [(eta6-C12H18)RuCl(fcdpm)] (3) [(eta5-C5Me5)RhCl(fcdpm)] (4) and [(eta5-C5Me5) IrCl(fcdpm)] (5) [fcdpm = 5-ferrocenyldipyrromethene]toward anticancer activity have been described. Binding of the complexes with calf thymus DNA (CT-DNA) and BSA (bovine serum albumin) have been thoroughly investigated by UV-Vis and fluorescence spectroscopy. Binding constants for 1-5 (range, 104-105 M-1) validated their efficient binding with CT-DNA Molecular docking studies revealed interaction through minor groove of the DNA, on the other hand these also interact through hydrophobic residues of the protein, particularly cavity in the subdomain IIA. In vitro anticancer activity have been scrutinized by MTT assay, acridine orange/ethidium bromide (AO/EtBr) fluorescence staining, and DNA ladder (fragmentation) assay against Dalton’s Lymphoma (DL) cells. Present study revealed that rhodium complex (4) is more effective relative to ruthenium (1-3) and iridium (5) complexes.

Five 3,5-difluorophenyl-substituted ruthenium complexes [Ru(bpy)2(dfpbpy)(ClO4)2] (Ru-Fbpy-bpy; bpy=bipyridine, dfpbpy=5,5?-di(3,5-difluorophenyl)-2,2?-bipyridine), [Ru(dpp)2(dfpbpy)(ClO4)2] (Ru-Fbpy-dpp; dpp=4,7-diphenyl-1,10-phenanthroline), [Ru(dpp)2(dfpphen)(ClO4)2] (Ru-Fphen-dpp; dfpphen=5,5?-di(3,5-difluorophenyl)-1,10-phenanthroline), [Ru(dpp)2(4,7-dfpphen)(ClO4)2] (Ru-Fdpp-dpp; 4,7-dfpphen=4,7-di(3,5-difluorophenyl)-1,10-phenanthroline), and [Ru(4,7-dfpphen)3(AsF6)2] (Ru-Fdpp) were synthesized, and their photophysical, electrochemical, and electroluminescent properties were studied systematically. The introduction of the electron-withdrawing group 3,5-difluorophenyl leads to a redshift of the emission of the ruthenium complexes. In addition, the 3,5-difluorophenyl substituent extends the pi conjugation of the ligand, and thus facilitates the metal-to-ligand charge-transfer process of the complexes. All the complexes display orange-red phosphorescent emissions centered at 638, 638, 624, 614, and 605 nm, respectively. Density functional theory calculations show that the lowest unoccupied molecular orbital of Ru-Fbpy-dpp, Ru-Fphen-dpp, and Ru-Fdpp-dpp are all distributed on the 3,5-difluorophenyl-substituted ligand. By using these complexes as emitters, highly luminescent single-layer devices are obtained. The optimized device based on Ru-Fdpp exhibits the highest luminous efficiency and power efficiency of 4.19 cd A-1 and 1.46 lm W-1, respectively. Bright ideas: Five 3,5-difluorophenyl-substituted ruthenium complexes have been synthesized and characterized. The photoluminescent efficiencies of the complexes improved after introduction of an electron-withdrawing substituent (see scheme). The complexes are suitable as dopant light-emitting materials for organic light-emitting diodes.

Synthetic Route of 32993-05-8, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 32993-05-8, C41H35ClP2Ru. A document type is Article, introducing its new discovery.

A series of p-cymene and cyclopentadienyl Ru(II)-aNHC complexes were synthesized from 2-methylimidazolium salts with either an N-bound alkenyl (1, 3) or picolyl tether (6, 7). The C(5)-Me substituted alkenyl-tethered analogues (2, 4) were also synthesized. Ag-mediated C(2)-dealkylation was a prominent side reaction that led to the formation of normally bound NHC Ru(II) complexes, which in selected cases were isolated (5, 8). A C(4)- over C(2)-selectivity for ruthenium binding was established by protecting the C(2)-position with an iPr group on the imidazolium precursor, for which unique p-cymene (9) and cyclopentadienyl (10) Ru(II)-aNHC derivatives were synthesized. All complexes were applied in the transfer hydrogenation of ketones and in secondary alcohol oxidation, with higher catalytic activity for the p-cymene over the cyclopentadienyl systems, as well as the alkenyl- over the picolyl-containing aNHC complexes.

Several new compounds of the type (1+) X(1-), where X = Cl, Br, I, I3, BPh4, p-toluenesulphonate, d(+)-campho-10-sulphonate, have been obtained in the form of ion pairs or salts.The above compounds form during oxidative addition by HX acids to CpOsH(PPh3)2.The reactions are complete after several seconds, with a quantitative yield.This is in contrast to the behaviour of CpRuH(PPh3)2, where covalent CpRuX(PPh3)2 forms.Reaction of CpOsH(PPh3)2 with DCl acid (excess) gives Cl, but no Cl is formed.Refluxing CpOsBr(PPh3)2, in ethylene glycol for instance, gives a (1+) cation as a result of the dehydrogenation of the glycol.Compounds of the type, X, in solutions of polar solvents (MeOH) or halogenated hydrocarbons (e.g.CH2X2) undergo transformation to CpOsX(PPh3)2 during the reductive elimination process.In this way novel CpOsI(PPh3)2 has been obtained.In the case of the reaction of a mixture of HX + X2 with CpOsH(PPh3)2, Br3 (for Br2) and I3 (for I2) have been obtained in the form of sparingly soluble ion pars with yields of about 90percent.

Two ruthenium hydride complexes commonly proposed as agents of unintended isomerization during olefin metathesis are examined for their activity in isomerization of estragole, a representative allylbenzene. Neither proves kinetically competent to account for the levels of isomerization observed during cross-metathesis of estragole by the second-generation Grubbs catalyst. A structure-activity analysis of selected ruthenium hydride complexes indicates that higher isomerization activity correlates with a more electrophilic metal center. It wasn’t me: Two Ru hydrides thought to trigger double-bond migration during olefin metathesis are examined for their isomerization activity. Neither can account for the high levels of undesired isomerization seen during self-metathesis of estragole, a model allylbenzene substrate. Higher activity is found to correlate with a less electron-rich Ru center. Copyright
