The palladium-catalyzed Friedel-Crafts-type alkylation of indoles in water has been achieved using amphiphilic polystyrene-poly(ethylene glycol) (PS-PEG) resin-supported phenanthroline-palladium complexes in water under aerobic conditions, affording the corresponding products with good-to-high yield. The polymeric catalyst was also found to promote the C3-alkylation reaction to give a thermodynamic alkylation product with high selectivity. The polymeric catalyst was recovered and reused several times without any loss of catalytic activity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: 1,10-Phenanthroline-5-carbaldehyde, you can also check out more blogs about91804-75-0

Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 131833-97-1, molcular formula is C17H30N2O2, introducing its new discovery. SDS of cas: 131833-97-1

Enoldiazosulfones undergo [3 + 3]-cycloaddition with nitrones when catalyzed by copper(I) catalysts, but not with dirhodium(II) catalysts. Under mild reaction conditions with chiral bisoxazoline ligands, copper(I) catalysts produce 1,2-oxazine-sulfone derivatives in high yields and enantioselectivities. Dirhodium(II) catalysts form stable donor-acceptor cyclopropenes that undergo uncatalyzed [3 + 2]-cycloaddition reactions with nitrones.

Four bichromophoric cyclometalated iridium complexes were synthesized and fully characterized. Their antiproliferative capacity against A549, HepG2 cells and HeLa cells as well as two human normal cells was studied by MTT assay. Rhodamine B modified complexes 2 and 4 were not cytotoxic to A549 cells while both rhodamine 6 g modified complexes 1 and 3 showed greater cytotoxicity than cisplatin. In particular, the antiproliferative activity of complex 3 was about 4.6 times than that of cisplatin. Thus, complex 3 was used for stability and pH sensitivity studies. The results indicated that the complex not only had rich fluorescence properties under acidic conditions, but also showed good stability. Further, interaction of complex with bovine serum albumin (BSA) has been investigated by UV?vis, fluorescence, synchronous fluorescence spectroscopy. The complexes have a certain ability to bind the BSA. Interestingly, these complexes can catalyze the reaction of the coenzyme NADH to NAD+, which is consistent with the apparent growth of ROS in cells. In addition, complex 3 can cause S phase arrest in the cell cycle, induce apoptosis, and affect mitochondrial membrane potential changes. Localization experiments of intracellular complexes by confocal microscopy suggested that these complexes enter cancer cells through energy dependence and specifically target the lysosomes, thus resulting in the damage of lysosomes.

A new photoluminescence (PL) probe based on a formyl bearing bis-cyclometalated Ir(iii) complex, [Ir(ppy)2phen-CHO]+PF6- (1), is synthesized and applied to the selective detection of a bisulfite anion (HSO3-). Probe 1 is prepared using 2-phenylpyridine (ppy) as the C^N main ligand and 1,10-phenanthroline-5-carboxaldehyde (phen-CHO) as the N^N ancillary ligand. Probe 1 displayed excellent selective PL enhancement in response to HSO3- in acetic acid-sodium acetate buffer solution (pH = 5.0). The increase of PL signal is directly proportional to the concentration of HSO3- in the range of 2 muM to 45 muM with a detection limit of 0.9 muM using 50 muM probe 1 and in the range of 0.5 muM to 6 muM with a detection limit of 0.3 muM using 10 muM probe 1. More importantly, probe 1 can respond to HSO3- rapidly within 40 s. Furthermore, probe 1 was successfully applied to detect HSO3- in real white wines and the bioimaging of HSO3- in living cells. The superior properties of probe 1 make it of great potential use for studying the effects of HSO3- in other biosystems.

A simple and sensitive electrogenerated chemiluminescence (ECL) sensor array was developed for the discrimination of three biothiols, including homocysteine (Hcy), cysteine (Cys) and glutathione (GSH) using two bis-cyclometalated Ir(III) complexes as ECL probes. Two aldehyde groups bearing bis-cyclometalated Ir(III) complexes were selected as ECL probes, including [(bt)2Ir(phen-CHO)]PF6 (bt = 2-phenylbenzothiazole, phen-CHO = 1,10-phenanthroline-5-carboxaldehyde, probe 1) and [(ppy)2Ir(phen-CHO)]PF6 (ppy = 2-phenylpyridine, probe 2). A ?signal on? ECL method was proposed for biothiols assay based on the increase in ECL intensity of two ECL probes by biothiols. Three biothiols can be detected with detection limits of 0.8, 0.7 and 0.8?muM by probe 1 and 0.3, 0.4 and 0.5?muM by probe 2 for Cys, Hcy and GSH, respectively. Two-element sensor array was assembled for the detection of three biothiols due to the different enhancement effects of biothiols on the ECL intensity of two ECL probes. The ECL sensor array combining with the principal component analysis was applied to discriminate three biothiols. This study demonstrates that the ECL sensor array using dual ECL reagents provides a promising way for the discrimination of multiple biothiols with good sensitivity and simpleness.

A long-lived aldol reaction-based iridium(III) chemosensor [Ir(ppy) 2 (5-CHOphen)]PF 6 (1, where ppy = 2-phenylpyridine and 5-CHOphen = 1,10-phenanthroline-5-carbaldehyde) for proline detection has been synthesized. The iridium(III) complex 1, incorporating an aldehyde group in N^N donor ligand, can take part in aldol reaction with acetone mediated by proline. The transformation of the sp 2-hybridized carbonyl group into a sp 3-hybridized alcohol group influences the metal-to-ligand charge-transfer (MLCT) state of the iridium(III) complex, resulting in a change in luminescence in response to proline. The interaction of the iridium(III) complex 1 with proline was investigated by 1 H NMR, HRMS and emission titration experiments. Upon the addition of proline to a solution of iridium(III) complex 1, a maximum 8-fold luminescence enhancement was observed. The luminescence signal of iridium(III) complex 1 could be recognized in strongly fluorescent media using time-resolved emission spectroscopy (TRES). The detection of proline in living cells was also demonstrated.

The catalytic, enantioselective cyclopropanation of cinnamyl alcohol has been accomplished with bis (iodomethyl)zinc in the presence of chiral bis(sulfonamides) derived from cyclohexanediamine. An extensive survey of diamine and sulfonamide structure has revealed a marked sensitivity to the spatial relationship of the amine groups, but only a modest dependence on the sulfonamide residue.

This review will cover the developments in the chemistry of phenanthroline-based ligands in the last 10-15 years. 1,10-Phenanthroline (phen) is a classic ligand in coordination chemistry, which couples versatility in metal ion binding with peculiar properties of its complexes. For instance, metal complexes with phenanthroline can be featured by an intense luminescence or can interact with DNA in an intercalative fashion inducing, in some cases, DNA cleavage. For this reason a number of phenanthroline-containing ligands has been recently synthesized by inserting phenanthroline within open-chain or macrocyclic backbone, in order to develop new molecular chemosensors for metal cations and anions, ionophores as well as new intercalating agents for polynucleotides. Furthermore, phenanthroline is rigid and its insertion within cyclic or acyclic structures can impart to the resulting ligand a high degree of pre-organization, affording selective complexing agents. This review will discuss on the coordination, luminescence and intercalating and/or DNA cleaving properties as well as on analytical applications of metal complexes with phenanthroline-based ligands. Particular attention will be devoted to macrocyclic receptors or open-chain ligands that, beside the phenanthroline nitrogen atoms, contain other donor atoms able to interact with the metal cations or anions.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 91804-75-0, and how the biochemistry of the body works.Electric Literature of 91804-75-0
