The reaction between trans-[AuF2(pyridine)2]+ and [PhI(pyridine)2]2+ results in the formation of PhIF2 and [Au(pyridine)4]3+. Investigation of the reaction pathway using model Pd and Pt analogs of the gold complex indicate the most likely mechanism is attack by the Au-F onto the I(III), rather than a redox process. This demonstrates that the Au(III)-F fragment can behave in a nucleophilic manner even in a relatively electron poor cationic complex.

Tristriazolotriazines with a threefold alkoxyphenyl substitution were prepared and studied by DSC, polarized optical microscopy (POM) and X-ray scattering. Six pentyloxy chains are sufficient to induce liquid-crystalline behavior in these star-shaped compounds Thermotropic properties of tristriazolotriazines with varying substitution patterns and a periphery of linear chains of different lengths, branching in the chain and swallow-tails, are compared. Generally, these disks display broad and stable thermotropic mesophases, with the tangential tristriazolotriazines being superior to the radial isomer.

The standard heats of formation of the crystalline compounds [PtL2X2] [L = NH2R (R = H, Me, CHMe2, Bu, Et, Pr, CH2CHMe2), en, pyridine; X = Cl, Br, I] were derived from the enthalpies of thermal decomposition of their cis isomers at elevated temperatures The enthalpy of sublimation (ΔHsub) of [PtL2Cl2] (L = pyridine) is estimated as 170 kJ/mol, which gives an average pyridine-Pt bond-dissociation enthalpy of 122 kJ/mol in the gas phase. For other amine ligands, the bond-dissociation enthalpy is less than for the pyridine complex, falling to a min. of 97 kJ/mol for NH3. These imply sublimation heats of 270-300 kJ/mol in the Cl complexes.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called CO2 Hydrogenation and Formic Acid Dehydrogenation Using Ir Catalysts with Amide-Based Ligands, published in 2020-05-11, which mentions a compound: 1452-77-3, Name is Picolinamide, Molecular C6H6N2O, Computed Properties of C6H6N2O.

A series of Ir catalysts [Cp*Ir(H2O)(QCXNHR)][SO4] (1-16; Q = 2-pyridyl, 4-hydroxy-2-pyridyl, 6-hydroxy-2-pyridyl, 2-imidazolyl, 1-pyrazolyl; X = O, S, NH; R = H, Me, Ph, 4-hydroxyphenyl) bearing amide-based ligands were isolated or generated in situ by a deprotonated amide moiety with the hypotheses that strong electron-donating ability of the coordinated anionic nitrogen atom and the proton-responsive OH group near the metal center will improve the catalytic activity for CO2 hydrogenation and formic acid (FA) dehydrogenation. The effects of the modifications of the ligand architecture on the catalytic activity were investigated for CO2 hydrogenation at ambient conditions (25° with 0.1 MPa H2/CO2 (volume/volume = 1/1)) and under slightly harsher conditions (50° with 1.0 MPa H2/CO2) in basic aqueous solutions together with deuterium kinetic isotope effects (KIEs) with selected catalysts. Complex [Cp*Ir(L12)(H2O)][HSO4] (12, L12 = 6-hydroxy-N-phenylpicolinamidate) that has an anionic coordinating N atom and an OH group in the second coordination sphere, exhibits a TOF of 198 h-1 based on the initial 1 h of reaction. This TOF which, to the best of our knowledge, is the highest value ever reported under ambient conditions in basic aqueous solutions However, complex [Cp*Ir(L10)(H2O)][HSO4] (L10 = 4-hydroxy-N-methylpicolinamidate) performs better in long-term CO2 hydrogenation (up to a TON of 14700 with [Ir] = 10μM after 348 h and the final formate concentration of 0.643 M with [Ir] = 250μM.) at ambient conditions. Further, the catalytic activity for FA dehydrogenation was examined under three different conditions (pH 1.6, 2.3 and 3.5). The complex 12 in any of these conditions is less active compared to the picolinamidate catalysts without ortho-OH, owing to its instability. Theor. calculations were performed to examine the catalytic mechanism, and a step-by-step mechanism has been proposed for both CO2 hydrogenation and FA dehydrogenation reactions. D. functional theory calculations of [Cp*Ir(L3)(H2O)][HSO4] (L3 = picolinamidate) and the X-ray structure of the [Cp*Ir(L7)(H)]•H2O (L7 = N-methylpicolinamidate) complex imply a pH-dependent conformational change from N,N coordination to N,O coordination upon lowering the pH of the aqueous solution
