Synthesis and characterization of chiral and achiral diamines containing one or two BODIPY molecules

The synthesis and characterization of one or two BODIPY fragments appended to four new chiral and one new achiral diamines is described. All of the examined BODIPY-appended diamines exhibit a quasireversible-irreversible reduction, with two reductions (separated by about 100 mV) observed in the case of diamines containing two BODIPY molecules. Only the BODIPY-appended ortho-phenylenediamines did not fluoresce under UV light. Computational analysis showed that the absence of fluorescence of the BODIPY-appended ortho-phenylenediamines is likely due to intramolecular quenching of the excited state electron within the phenylenediamine ligand. Computational analysis also showed that the incorporation of a BODIPY molecule greatly reduces the basicity of the amine center, by about 10-14 pKa units. The BODIPY moiety was found to be more electron withdrawing than a tosyl and a pentafluorophenyl group, suggesting why excess metals are needed in heavy metal sensor applications (heteroatom-appended BODIPYs = poor ligands). An improved procedure for the scalable synthesis (greater than three grams) of 8-methanethio-BODIPY, a common starting material for the generation of heteroatom-appended BODIPY molecules, is also described.

A Binaphthyl-Based Scaffold for a Chiral Dirhodium(II) Biscarboxylate Ligand with alpha-Quaternary Carbon Centers

A chiral dirhodium(II) paddlewheel complex has been synthesized from biscarboxylate ligands derived from BINOL, and the resulting complex has been used in enantioselective carbene/alkyne cascade reactions. The ligand design was guided by requirements of alpha,alpha-dimethyl substituted carboxylates and bidentate ligands to ensure high levels of catalytic activity. Previously disclosed chiral complexes lack these features, resulting in low product yields. The design successfully replicated or exceeded the yields of the unusually effective achiral catalyst for the cascade reaction, Rh2(esp)2, which often shows unique reactivity. Promising enantioselectivity was observed for aldehyde-derived hydrazone substrates (29-96% ee), showing that the new scaffold has significant potential.

Effect of nitrogen position of carboline on the device performances of blue phosphorescent organic light-emitting diodes

A delta-carboline derived compound, 5-(3?-(9-carbazolyl)-[1,1?-biphenyl]-3-yl)pyrido[3,2-b]indole, was synthesized as a high triplet energy bipolar host material for blue phosphorescent organic light-emitting didoes and it was compared with alpha-carboline derived host material with the same backbone structure. The delta-carboline derived host material showed better electron transport properties than the host with alpha-carboline due to better electron accepting properties. Therefore, the new host material reduced driving voltage and increased the power efficiency of blue phosphorescent organic light-emitting diodes compared to a standard host with alpha-carboline moiety. A high external quantum efficiency of 25.3% and a high power efficiency of 36.4 lm/W were achieved in the blue phosphorescent organic light-emitting diodes.

Dihydrogen, dihydride and in between: NMR and structural properties of iron group complexes

Tabulating the structures and characteristic NMR properties of 17 iron complexes, 98 ruthenium complexes and 70 osmium complexes that contain dihydrogen or compressed dihydride ligands reveals a variety of trends. The H{single bond}H bond lengths increase from similar Fe(II) to Ru(II) to Os(II) complexes. Iron(II) displays a narrow range of H{single bond}H distances for stable complexes. Electronegative atoms Cl and O, when attached on the metal trans to the dihydrogen ligand, result in elongation of the H{single bond}H bond relative to more electropositive atoms H, C, P and N. The family of cyclopentadienyl ligands also causes this elongating effect. The dihydrogen ligands with short H{single bond}H distances and weak interactions with the metal, especially on iron and ruthenium are in the fast spinning regime. One exception is the biporphyrin complex of ruthenium with the side-on bridging H2 ligand which has an H{single bond}H distance of 118 pm but is in the fast spinning regime. There are some ruthenium complexes with H{single bond}H distances greater than 110 pm that are in the slow motion regime and several complexes of osmium with H{single bond}H distances greater than 130 pm that are in this regime. The large JHH due to quantum mechanical exchange coupling are observable for some of these osmium complexes with H{single bond}H distances in the range of 140-160 pm. The dihydrogen ligands in many complexes appear to have librational motions or other motions that place them in the intermediate motion regime. New equations to correlate JHD with H{single bond}H distances for ruthenium dihydrogen complexes and for osmium dihydrogen complexes are introduced here.

Design of Iron Coordination Complexes as Highly Active Homogenous Water Oxidation Catalysts by Deuteration of Oxidation-Sensitive Sites

The nature of the oxidizing species in water oxidation reactions with chemical oxidants catalyzed by alpha-[Fe(OTf)2(mcp)] (1alpha mcp = N,N?-dimethyl-N,N?-bis(pyridin-2-ylmethyl)cyclohexane-1,2-diamine, OTf = trifluoromethanesulfonate anion) and beta-[Fe(OTf)2(mcp)] (1beta) has been investigated. Moessbauer spectroscopy provides definitive evidence that 1alpha and 1beta generate oxoiron(IV) species as the resting state. Decomposition paths of the catalysts have been investigated by identifying and quantifying ligand fragments that form upon degradation. This analysis correlates the water oxidation activity of 1alpha and 1beta with stability against oxidative damage of the ligand via aliphatic C-H oxidation. The site of degradation and the relative stability against oxidative degradation are shown to be dependent on the topology of the catalyst. Furthermore, the mechanisms of catalyst degradation have been rationalized by computational analyses, which also explain why the topology of the catalyst enforces different oxidation-sensitive sites. This information has served in creating catalysts where sensitive C-H bonds have been replaced by C-D bonds. The deuterated analogues D4-alpha-[Fe(OTf)2(mcp)] (D4-1alpha), D4-beta-[Fe(OTf)2(mcp)] (D4-1beta), and D6-beta-[Fe(OTf)2(mcp)] (D6-1beta) were prepared, and their catalytic activity has been studied. D4-1alpha proves to be an extraordinarily active and efficient catalyst (up to 91% of O2 yield); it exhibits initial reaction rates identical with those of its protio analogue, but it is substantially more robust toward oxidative degradation and yields more than 3400 TON (n(O2)/n(Fe)). Altogether this evidences that the water oxidation catalytic activity is performed by a well-defined coordination complex and not by iron oxides formed after oxidative degradation of the ligands.

Nucleolar Stress Induction by Oxaliplatin and Derivatives

Platinum(II) compounds are a critical class of chemotherapeutic agents. Recent studies have highlighted the ability of a subset of Pt(II) compounds, including oxaliplatin but not cisplatin, to induce cytotoxicity via nucleolar stress rather than a canonical DNA damage response. In this study, influential properties of Pt(II) compounds were investigated using redistribution of nucleophosmin (NPM1) as a marker of nucleolar stress. NPM1 assays were coupled to calculated and measured properties such as compound size and hydrophobicity. The oxalate leaving group of oxaliplatin is not required for NPM1 redistribution. Interestingly, although changes in diaminocyclohexane (DACH) ligand ring size and aromaticity can be tolerated, ring orientation appears important for stress induction. The specificity of ligand requirements provides insight into the striking ability of only certain Pt(II) compounds to activate nucleolar processes.
