A novel chemiluminescence (CL) system, including the cyclometallated iridium(III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium}, potassium permanganate and oxalic acid, is proposed for the determination of benzenediols. This method is based on the fact that hydroquinone and catechol exhibited an inhibiting effect, while resorcinol exhibited an enhancing effect on CL intensity. The optimum conditions for CL emission were investigated. Under optimal conditions, the detection limits of hydroquinone, catechol and resorcinol were 6.4?x?10-8, 2.7?x?10-9 and 8.1?x?10-7?mol/L, respectively. The method has been successfully applied to the determination of benzenediols in different types of water sample. The luminophors of the CL systems were all identified as the metalligand charge-transfer (MLCT) excited state of the iridium complex. Copyright (c) 2011 John Wiley & Sons, Ltd.

In a document, author is Gan, Min.

Amino-acid-derived phthalazine catalysts have been designed and synthesized for enantioselective halolactonization of prochiral dienoic acids. The scope of the reaction is evidenced by 17 examples of Spiro a-exo-methylene-halolactones with up to 99.8% enantiomeric excess. The resulting enantio-enriched Spiro halolactone products are found to exhibit potent antitumor effects. In addition, both antipodes of products with equally excellent enantioselevity could be obtained since a pair of enantiomeric catalysts is guaranteed.

Synthetic Route of 1078-61-1, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 1078-61-1.

In a document, author is Liu, Hai-Jie, introduce the new discover, Related Products of 5267-64-1.

A new CNNC carbene-phthalazine tetradentate ligand has been synthesised, which in the reaction with [Ru(T)Cl-3] (T = trpy, tpm, bpea; trpy = 2,2′; 6′, 2”’-terpyridine; tpm = tris(pyrazol-1-yl)methane; bpea = N, N-bis(pyridin-2-ylmethyl) ethanamine) in MeOH or iPrOH undergoes a C-N bond scission due to the nucleophilic attack of a solvent molecule, with the subsequent formation of the mononuclear complexes cis-[Ru(PhthaPz-OR)(trpy) X](n+), [Ru(PhthaPz-OMe)(tpm) X](n+) and trans, fac-[Ru(PhthaPz-OMe) (bpea) X] n+ (X = Cl, n = 1; X = H2O, n = 2; PhthaPz-OR = 1-(4-alkoxyphthalazin-1-yl)-3-methyl-1H-imidazol- 3-ium), named 1a(+)/2a(2+) (R = Me), 1b(+)/2b(2+) (R = iPr), 3(+)/4(2+) and 5(+)/6(2+), respectively. Interestingly, regulation of the stability regions of different Ru oxidation states is obtained by different ligand combinations, going from 6(2+), where Ru(III) is clearly stable and mono-electronic transfers are favoured, to 2a(2+)/2b(2+), where Ru(III) is almost unstable with regard to its disproportionation. The catalytic performance of the Ru-OH2 complexes in chemical water oxidation at pH 1.0 points to poor stability (ligand oxidation), with subsequent evolution of CO2 together with O-2, especially for 4(2+) and 6(2+). In electrochemically driven water oxidation, the highest TOF values are obtained for 2a(2+) at pH 1.0. In alkene epoxidation, complexes favouring bi-electronic transfer processes show better performances and selectivities than those favouring mono-electronic transfers, while alkenes containing electron-donor groups show better performances than those bearing electron-withdrawing groups. Finally, when cis-beta-methylstyrene is employed as the substrate, no cis/trans isomerization takes place, thus indicating the existence of a stereospecific process.
