Walker, S. Brett,Lewis, Jennifer A.
, p. 1419 - 1421 (2012)
Reactive silver inks for printing highly conductive features (>10 4 S/cm) at room temperature have been created. These inks are stable, particle-free, and suitable for a wide range of patterning techniques. Upon annealing at 90 °C, the printed electrodes exhibit an electrical conductivity equivalent to that of bulk silver.

, p. 813 - 816 (2007)
Thermal decomposition of silver acetate was studied (TG, DSC, mass-spectrometry, X-ray analysis, electron microscopy). Non-isothermal thermogravimetric data (obtained at two different rates of linear heating) were used for kinetic studies. Kinetic paramet
Free Amino Group-Directed γ-C(sp3)-H Arylation of α-Amino Esters with Diaryliodonium Triflates by Palladium Catalysis

Free amino group-directed C(sp3)-H functionalization of aliphatic amines is a fundamental challenge in synthetic organic chemistry. Also, the NH2-directed C(sp3)-H functionalization of α-amino acids and their derivatives remains barely explored. With palladium as the catalyst and Ag2O as the additive, we developed the first NH2-directed γ-C(sp3)-H arylation of α-amino esters with diaryliodonium triflates for the construction of synthetically useful γ-aryl-α-amino esters, and the result of the KIE study suggested that the catalytic reaction involved an irreversible C-H cleavage as the rate-determining step.

New asymmetric trans-platinum(ii) complexes, composed of an isopropylamine, an azole and two carboxylate leaving groups, are presented. The crystal and molecular structures of one of the complexes has been determined and the cytotoxicity and reactivity with 5′-guanosine monophosphate is reported. The complexes show a reduced reactivity, but no decrease in cytotoxic activity compared to their chloro-counterparts. Furthermore the complexes largely overcome cisplatin resistance, they therefore present an interesting class of antitumour active trans-platinum complexes. The Royal Society of Chemistry 2006.
Impact of counterions on micelle formation and polymerization of 11-acryloyloxyundecyltrimethylammonium surfactants
Bilibin, A. Yu,Fetin, P. A.,Fetina, V. I.,Lezov, A. A.,Zorin, I. M.
, (2020/04/20)
New surfactants based on the cationic monomer 11-acryloyloxyundecyltrimethylammonium with counterions bromide, nitrate, acetate, camphorsulfonate, 4-toluenesulfonate, trifluoroacetate were obtained in this work. In most cases counterions change the critical micelle concentration by 2–3 times (being compared with bromide) except sample with acetate counterions (in this case critical micelle concentration increases by an order of magnitude). Substitution of bromide for hydrophobic counterions (toluenesulfonate, trifluoroacetate, camphorsulfonate) does not lead to expected transformation of spherical micelles to long wormlike micelles. The polymerization of such monomers occurs according to the microemulsion mechanism involving micelles of monomers.

A novel site-selective palladium-catalyzed oxidative C8-H homocoupling reaction of quinoline N-oxides has been developed. The reaction affords substituted 8,8′-biquinolyl N,N′-dioxides that can be readily converted to a variety of functionalized 8,8′-biquinolyls. Mechanistic studies point to the crucial role of the oxidant and a non-innocent behavior of acetic acid as a solvent.

The reaction between Pd3(OOCMe)6 and Ag 2(OOCMe)2 afforded the first palladium-silver heterometallic acetate-bridged complex PdII[(μ-OOCMe) 2AgI(HOOCMe)2]2 (1). The molecular geometry and electronic structure of 1 were studied by single-crystal XRD and quantum-chemical DFT calculations. Thermal transformations of 1 in vacuo and under Ar, H2 produced PdAg alloy nanoparticles characterized with powder XRD and EXAFS.

Two types of palladium nitrosyl carboxylate complexes were synthesized and their structures were characterized by several methods including an X-ray diffraction analysis. The tetranuclear complexes Pd4(μ-NO) 2(OCOR)6 (R=CMe3, Me, Ph, CHMe2, CH2Cl, IIa-e, respectively) were synthesized by the reaction of Pd(NO)Cl with silver carboxylates Ag(OCOR). The structure of IIa was determined by a single crystal X-ray diffractometry. Crystals of IIa are monoclinic, space group P21/n, a=12.104(7), b=23.970(8), c=15.495(4) A?, β=90.30(4)°, V=4496(4) A?3. The least-square structure refinement on F2 was converged to R=0.0714 for 6228 reflections [I>2σ(I)]. In IIa the palladium atoms form near regular rectangle Pd4, with the edges bridged by the ligands. Two bridging NO groups occupying the opposite sides of the rectangle are in the cis-positions with respect to the Pd4 plane. These groups are symmetric, with the Pd-N-O angles ranging from 120.4(5) to 121.8(5)°. The coordination polyhedrons of the Pd atoms are close to square planar ones. The reaction of the Pd4(CO)4(OCOCF3)4 clusters with nitrogen monoxide leads to a substitution of the carbonyl groups and formation of the low stable complex Pd4(NO)4(OCOCF3) 4 (III) that was characterized by the spectroscopic and analytical data. The transformation of III during slow recrystallization from toluene gives Pd3(NO)2(OCOCF3) 4·2C6H5Me (IV) and palladium black. The structure of IV was determined by an X-ray diffraction analysis. Crystals of IV are monoclinic, space group P21/n, a=9.2340(2), b=9.2859(2), c=18.0460(4) A?, β=92.339(1)°, V=1546.08(6) A?3. The least-square refinement on F2 was converged to R=0.0205 for 3209 reflections [I>2σ(I)]. In the linear tri-nuclear molecule of IV, any adjacent metal atoms are linked with a couple of the CF3CO 2 ligands and are separated by 3.0755(2) A?. Additionally, the terminal Pd atoms bear the NO and the η2-toluene ligands. The configuration of the N atoms corresponds to the ideal sp2- hybridization. The Pd-N-O angle is 117.2(2)°. The N atoms form short contacts with the aromatic rings. The distance between the center of the ring and the nitrogen atom is 2.70 A?. Complex IV is the first example of the Pd complex with the terminal nitrosyl ligand. The scheme of transformation of complex III to complex IV was proposed.

Silver carboxylates [Ag(O2CR): R = Me, tBu, 2,4,6-Me3C6H2], fluorocarboxlyates [Ag(O2CRf): rf = c3f7, C6F13, C7F15] and their phosphine adducts [Ag(O2CR)·nPR3′: r = me, tBu, 2,4,6-Me3C6H2, R′ = Me, Ph, n = 2; R = Me, R′ = Me, n = 3; Ag(O2CRf).2PPh3, Rf = C3F7, C6F13, C7F15] have been synthesised, characterised spectroscopically and used as precursors in the aerosol-assisted chemical vapour deposition of silver films. All the phosphine adducts produced films, though in general PMe3 adducts, proved more successful than PPh3 analogues. The fluoro-carboxylates and their PPh3 adducts all generated silver films, though the growth rate for the adducts was lower. All these latter films showed carbon impurities while fluorine was also evident in most cases. The X-ray structure of AgO2CC3F7·2PPh3 is also reported.
