Abstract:

A series of 12 new copper-based photocatalysts of the type Cu(N^N)(P^P)BF4 were synthesized bearing π-extended diimine ligands. The complexes have red shifted absorptions and larger extinction coefficients than complexes prepared with a parent diimine, dmp. The complexes were evaluated for their ability to promote three different photochemical transformations. Although the complexes were inactive in a reductive PCET process, the complexes afforded good yields in both SET and ET processes. Interestingly, homoleptic copper-complexes derived from the π-extended diimines were significantly more ac

Abstract:

Wolff–Kishner reduction reactions were investigated by DFT calculations for the first time. B3LYP/6-311+G(d,p) SCRF=(PCM, solvent = 1,2-ethanediol) optimizations were carried out. To investigate the role of the base catalyst, the base-free reaction was examined by the use of acetone, hydrazine (H2N–NH2) and (H2O)8. A ready reaction channel of acetone → acetone hydrazine (Me2C=N–NH2) was obtained. The channel involves two likely proton-transfer routes. However, it was found that the base-free reaction was unlikely at the N2 extrusion step from the isopropyl diimine intermediate (Me2C(H)–N=N–H).

The chelating diimine core of the title compound deviates slightly from planarity, with an N—C—C—N torsion angle of 5.3 (3)°. Delocalization in the diimine core is indicated by N—C and C—C bonds that are, respectively, longer and shorter than those found in related nonchelating diimines. The distorted square-planar coordination environment around the PdIIatom is manifested as bond angles that are smaller

Abstract:

Metal-ligand complexes have attracted major interest due to their potential medical applications as anticancer agents. The work described in the current article aimed to synthesize, spectroscopic, thermal, and biological studies of some metal-diimine complexes. A diimine ligand, namely 2-{[2-(4-chlorophenyl)-2-hydroxyvinyl]-hydrazonomethyl}phenol (diim) was prepared via the reaction of p-chlorophenacyl bromide with hydrazine hydrate in ethanol, then condensation was completed with 2-hydroxybenzaldehyde in acetic acid. The Co(II), Ni(II), Cu(II), and Zn(II) complexes were prepared with a metal:

Condensation of α-diketones (2,3-butanedione, benzil, and acenaphthenequinone) with 3-H2NC6H4Bpin (pin = 1,2-O2C2Me4) gave the corresponding boron-containing α-diimines. The addition of these ligands to [MCl2(coe)]2 (coe = cis-cyclooctene, M = Pd or Pt) gave complexes of the type cis-MCl2(α-diimine) in moderate to high yields. The platinum complexes have been examined for their ability to bind to DNA using enzyme digest studies. These complexes were found to bind to single-stranded DNA as well as, or better than, the non-boron containing controls, and showed binding similar to that of cisplati

Both ligands crystallize with the –N=C(R)—C(R)=N– group around an inversion centre, in atransconfiguration.

Their stability is strongly determined by the π-acceptor ability of the reducible α-diimine ligand, which decreases in the order μ-bpym > bpym >> bpy. Along this series, increasing delocalisation of the odd electron density in the radical anion over the Os(α-diimine) chelate ring causes weakening of the axial (CO)4Os-Os(CO)2(α-diimine) bond and its facile cleavage

Abstract:

The electrooxidation of the adenosine antagonist 1-methylxanthine has been studied in the pH range 2·5–10·7 at the pyrolytic graphite electrode. The initial 4e, 4H+ oxidation step leads to the formation of an unstable diimine, for which the half-life was found to be 1·8 s by chronoamperometry. The diimine is readily attacked by water to give a carbinolamine which decomposes in a pseudo first-order reaction to give, as the major products, 1-methylalloxan at pH 3·0 and 5-hydroxy-5-(methylcarbamoyl)hydantoin at pH 7·0. The oxidation products were identified. The diimine can also be reversibly red

Abstract:

The diimine-dioxime ligand, 4,9-diaza-3,10-diethyl-3,9-dodecadiene-2,11-dione bisoxime (LH2), containing a N4 donor set was prepared by Schiff base condensation of 2-hydroxyimino-3-pentanone and 1,4-diaminobutane in two ways: in protic and in aprotic solvent. Higher yield of (LH2) imine was obtained when the synthesis was carried out using protic solvent (C2H5OH) instead of aprotic benzene (78% and 30%, respectively). Cu(II) metal complex of diimine-dioxime was synthesized in CH3OH from metal salt and LH2 in mole ratio 1:1. The isolated complex was characterized by the elemental analysis, IR s

Abstract:

The influences of ZnEt2 on ethylene chain transfer polymerization were investigated in detail and the polymerization mechanism was thoroughly analyzed. The results indicated that ZnEt2 contributed greatly to increase the activity of α-diimine nickel complex/ZnEt2/MAO(MAO: methylaluminoxane). It was striking that α-diimine nickel complex/ZnEt2 catalyst system (1/100 mol/mol) exhibited 8.0 ×104g/mol∙h activity, it was possible the formation of the ion pairs of Nickel and Zinc was convenient for ethylene chain propagation, however, the ion pairs were unstable in ethylene polymerization.

Abstract:

(3R,4R,5R,6R)-3,6-Diphenyl-N,N'-bis[(S)-1-phenylethyl]octa-1,7-diene-4,5-diamine, by treatment with organolithium reagents RLi in controlled experimental conditions, underwent rearrangement and/or substitution of one or two branched allyl(s) by the R group(s). Hence, this diene behaves as a masked form of the chiral glyoxal diimine from that it is prepared, allowing the preparation of C1-symmetric 1,2-disubstituted 1,2-diamines, which are generally not available by the direct addition of organometallic reagents to the diimine, and C2-symmetric 1,2-diamines with good diastereoselectivities.

Abstract:

The reaction of CpML2Cl (M = Fe, L = CO; M = Cr, L = NO) with benzil diimine (H2BDI) (2) derived from benzil-bis(trimethylsilyl)diimine (Si2BDI) (1) in a 1 : 3 and 1 : 2 molar ratio in the presence of excess AgO3SCF3 (= AgOTf) resulted in the formation of the new cationic tris- and bisbenzildiimine complexes [Fe(H2BDI)3]X2 (3) and [CpCr(H2BDI)2]X2 (X = OTf) (4), respectively. The addition of AgO3SCF3 is necessary in both cases to abstract chloride. Unusual in the first case is the total replacement of ligands of CpFe(CO)2Cl and in the second case the oxidation of Cr(0) to Cr(III) leading to th
