Template-directed synthesis of a covalent organic capsule based on a 3 nm-sized metallocapsule

(Figure Presented) A 4 nm-sized covalent organic capsule having 24 pyridyl groups was synthesized in extremely high yield (43% in three steps) using an octahedron-shaped metallocapsule as a template molecule. The entity was fully characterized by NMR and MALDI-TOF MS measurements. N-Methylation of the 24 pyridyl groups of the organic capsule produced a 5 nm-sized polycationic capsule, which is larger than the neutral precursory capsule because of the electrostatic repulsion between the positive charges on the pyridinium groups of the capsule.

Enantioselective C2-Alkylation of Indoles through a Redox-Relay Heck Reaction of 2-Indole Triflates

A palladium-catalyzed enantioselective redox-relay Heck reaction of 2-indole triflates and disubstituted alkenes is reported. This process combines readily available indole triflates with a variety of alkenes to afford a range of indole derivatives bearing a stereocenter adjacent to C2. Enantioselectivity is achieved through use of a simple pyridine-oxazoline ligand. Tuning the electronics of the indole, through judicious choice of N-protecting group, is required to ensure selective beta-hydride elimination away from the indole core. Utility of this method is highlighted in a modular formal synthesis of an S1P1 agonist precursor developed by Merck.

Synthesis, characterization, and butadiene polymerization of iron(III), iron(II) and cobalt(II) chlorides bearing 2,6-bis(2-benzimidazolyl)pyridyl or 2,6-bis(pyrazol)pyridine ligand

Iron(III), iron(II) and cobalt(II) complexes bearing neutral N,N,N-tridentate ligand (Fe(III)L1, 1a; Fe(III)L2, 1b; Fe(III)L3, 1c; Fe(III)L4, 2a; Fe(III)L5, 2b; Fe(III)L6, 2c; Fe(II)L1, 3a; Fe(II)L2, 3b; Fe(II)L3, 3c; Fe(II)L4, 4a; Fe(II)L5, 4b; Fe(II)L6, 4c; CoL1, 5a; CoL2, 5b; CoL3, 5c; CoL5, 6b and CoL6, 6c) have been synthesized from the metal chlorides (FeCl3, FeCl2¡¤4H2O or CoCl2) by treating the corresponding ligands (2,6-bis(benzimidazol-2-yl)pyridine, L1; 2,6-bis(1?-ethylbenzimidazol-2?-yl)pyridine, L2; 2,6-bis(1?-benzylbenzimidazol-2?-yl)pyridine, L3; 2,6-bis(pyrazol)pyridine L4; 2,6-bis(3-methylpyrazol)pyridine, L5 or 2,6-bis(3,5-dimethylpyrazol)pyridine, L6. The complexes are characterized by FTIR and elemental analyses. The structures of complexes 1a, 1b, 3a, 3b, 3c, 4a, 5a, 5b, 5c and 6c are further confirmed by X-ray crystallographic analyses. Six coordination iron(III) (1a, 1b and 1c) and iron(II) (3c*DMF) complexes adopt a distorted octahedral configuration with the equatorial plane formed by the three nitrogen atoms and one chlorine atom, while the iron(II) (3a, 3b and 4a) and cobalt complexes (5a, 5b, 5c and 6c) adopt a trigonal bipyramidal configuration with the equatorial plane formed by the pyridyl nitrogen atoms and the two chlorine atoms. All complexes are evaluated as precursors for 1,3-butadiene polymerization in the presence of cocatalyst in toluene at room temperature. Iron(III) and iron(II) bearing the same ligand show comparable catalytic performance. The catalytic activity and selectivity are significantly influenced by the ligand structure, with the latter being tunable within a wide range from cis-1,4 to trans-1,4. Cobalt complexes, in combination with either MAO or aluminum chlorides shown high activity, and high cis-1,4-selectivity irrespective of the structure of ligand backbone.

Novel palladium(ii) and platinum(ii) complexes of 5,5-diethylbarbiturate (barb) with 2-phenylpyridine (Hppy), 2,2?-bipyridine (bpy) and 2,2?-dipyridylamine (dpya) have been prepared and characterized by elemental analysis, IR, UV-Vis, NMR and ESI-MS. Single-crystal diffraction measurements show that complex 1 consists of binuclear [Pd2(mu-barb-kappaN,O)2(ppy-kappaN,C)2] moieties, while complexes 3-5 are mononuclear, [M(barb-kappaN)2(L-kappaN,N?)] (L = bpy or dpya). 6 has a composition of [Pt(dpya-kappaN,N?)2][Ag(barb-kappaN)2]2¡¤4H2O and 2 was assumed to have a structure of [Pt(barb-kappaN)(Hppy-kappaN)(ppy-kappaN,C)]¡¤3H2O. The complexes were found to exhibit significant DNA binding affinity by a non-covalent binding mode, in accordance with molecular docking studies. In addition, complexes 1 and 2 displayed strong binding with supercoiled pUC19 plasmid DNA. Cellular uptake studies were performed to assess the subcellular localization of the selected complexes. A moderate radical scavenging activity of 1 and 2 was confirmed by DPPH and ABTS tests. Complexes 1, 2, and 5 showed selectivity against HT-29 (colon) cell line.

Enhanced Thermoelectric Performance of Conjugated Polymer/Single-Walled Carbon Nanotube Composites with Strong Stacking

We design and synthesize a novel donor-acceptor-type BDT-based conjugated polymer,PBDTDTffBT, and prepare composite films containing single-walled carbon nanotubes (SWCNTs) and the PBDTDTffBT polymer. Strong pi-pi interfacial interactions are present between the PBDTDTffBT polymer and the SWCNTs, and we systematically study the effects of different mass ratios of PBDTDTffBT to SWCNTs on the thermoelectric (TE) properties. The maximum electrical conductivity, Seebeck coefficient, power factor, and ZT value of the composite films are 529.3 S cm-1, 68.1 muV K-1, 80.9 muW m-1 K-2, and 0.028 at room temperature, respectively. Additionally, the composite film with a PBDTDTffBT:SWCNT mass ratio of 1:10 exhibits the highest power factor of 116.7 muW m-1 K-2 at approximately 95 C. This study has a large potential to broaden the research scope of composite TE materials.
