The Solvent Extraction Study of a Dibenzo-18-crown-6 Complex with Silver Picrate

The extraction constant of the silver ion-dibenzo-18-crown-6 (DB18C6) complex between benzene and water and the complex-formation constant of DB18C6 with silver picrate in benzene were determined at 25 deg C.The Ag+-DB18C6 complex is much more extractable than the Ag+-18-crown-6 one.The Ag+-DB18C6 complex is much more stable for benzene than for aqueous solutions.

Enantioselective Trapping of Oxonium Ylides by 3-Hydroxyisoindolinones via a Formal SN1 Pathway for Construction of Contiguous Quaternary Stereocenters

An enantioselective Rh(II)/chiral phosphoric acid co-catalyzed three-component reaction via trapping of oxonium ylides with 3-hydroxyisoindolinones by a formal SN1 pathway is described. This reaction allows for the efficient synthesis of isoindolinone derivatives with two contiguous quaternary stereogenic centers in high yields (up to 93%) with excellent enantioselectivities and moderate diastereoselectivities under mild reaction conditions.

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.Computed Properties of C20H13O4P, you can also check out more blogs about39648-67-4

Perylene diimide isomers containing a simple sp3-core for non-fullerene-based polymer solar cells

In order to investigate the effect of the geometries of perylene diimide (PDI)-based small molecules, five different isomers were synthesized by using a cyclohexane core as a simple sp3-sigma core. Diaminocylohexane is such an effective core for the systematic development of many kinds of isomers via geometric tuning as well as for reducing the self-aggregation tendency of PDIs. Depending on the anchoring position of the PDI units on the cyclohexane core (ortho-, meta- and para-), isomers exhibited differences in solubility and crystallinity. Among the studied isomers, ortho-substituted t-OCP was found to have a highly twisted molecular structure which minimizes the strong tendency towards crystallization due to individual PDI moieties. The unique geometrical nature of the t-OCP isomer led to the highest power conversion efficiency (PCE = 6.23%) of bulk heterojunction (BHJ) polymer solar cells (PSCs) with a higher short-circuit current density (Jsc) and fill factor (FF). It is mainly ascribed to the formation of a nanophase interpenetrating network with well-balanced carrier mobility in the blend film.

The stereodivergent synthesis of chiral 4,5-disubstituted pybox ligands

(1R,2S)-2-Amino-1,2-diphenylethanol and (1R,2S)-norephedrine are synthons for the stereodivergent syntheses of pybox ligands. The trans-isomers have been synthesised previously from the corresponding bis-amides derived from pyridine-2,6-dicarbonyl dichloride, the cis-4,5-disubstituted isomers are prepared for the first time from the same aminols and dimethyl pyridine-2,6-dicarboximidate. This protocol is also suitable for the synthesis of pybox derived from (S)-methioninol and (2S)-2-amino-2-(2?-naphthyl)ethanol.

Syntheses of Square-planar Nickel-(II) and -(I) Complexes of an Octaaza Macrohexacyclic Ligand and Crystal Structure of the Nickel(II) Complex

The square-planar nickel(II) complex of the octaaza macrohexacyclic ligand 1,3,6,8,10,12,15,17-octaazahexacyclo<15.6.1.1 3,17 .1 6,0 .1 8,12 .0 18,23 >heptacosane, 2, has been synthesized by template condensation of the nickel(II) complex of 3,7-bis(2-aminoethyl)-1,3,5,7-tetraazabicyclo<3.3.1>nonane with formaldehyde and trans-cyclohexane-1,2-diamine.The complex exhibits an unusually strong ligand-field strength compared with other square-planar nickel(II) complexes of 14-membered azamacrocycles.Cyclic voltammetry indicated a one-electron reduction potential at -1.32 V vs.Ag-AgCl and no oxidation peak up to +1.59 V.The complex crystallizes in the orthorhombic space group Pna2 1 , with a = 17.934(2), b = 16.056(3), c = 9.612(1) Angstroem and Z = 4.The structure was solved by the heavy-atom method and refined by full-matrix least squares to a final R = 0.0447 for 2092 observed 2?(I)> reflections.The ligand contains bicyclononane and tricyclotetradecane cage ring moieties fused at both ends of two ethylenediamine groups.The average Ni-N distance is 1.904(7) Angstroem.The N-N bite distances are 2.706(6) and 2.698(6) Angstroem for the five-membered chelate rings and 2.703(6) and 2.665(6) Angstroem for the six-membered chelate rings so that the cavity size of the ligand is similar to that of 1,4,7,10-tetraazacyclododecane.Reduction of 2 with Na/Hg gave PF6, which shows an anisotropic axial EPR powder spectrum with g values of g <*> > g <*> .
