A new Co(II) complex of general formula [Co(L)2] has been synthesized from a NNO tridentate Schiff base ligand, 2-[(piperidin-2-ylmethylimino)-methyl]-phenol (L). The title complex is characterized by elemental, spectroscopic, antibacterial, and single crystal X-ray structural studies. X-Ray crystallography reveals that the complex shows a distorted octahedral geometry around the Co(II) ion. The complex was tested against several bacteria and shows good antibacterial activities against almost all of the bacteria. The interactions of the title complex with calf thymus deoxyribonucleic acid (CT-DNA) have been investigated by electronic absorption and fluorescence spectroscopy, showing that the complex interacts with CT-DNA via partial intercalation. Thermogravimetric analysis (TGA) of the complex has also been reported and the result shows that the complex is thermally stable up to 134 C.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 22990-77-8 is helpful to your research. name: 2-Piperidylmethylamine

Supported by increasingly available reserves, natural gas is achieving greater adoption as a cleaner-burning alternative to coal in the power sector. As a result, carbon capture and sequestration from natural gas-fired power plants is an attractive strategy to mitigate global anthropogenic CO2 emissions. However, the separation of CO2 from other components in the flue streams of gas-fired power plants is particularly challenging due to the low CO2 partial pressure (?40 mbar), which necessitates that candidate separation materials bind CO2 strongly at low partial pressures (?4 mbar) to capture ?90% of the emitted CO2. High partial pressures of O2 (120 mbar) and water (80 mbar) in these flue streams have also presented significant barriers to the deployment of new technologies for CO2 capture from gas-fired power plants. Here, we demonstrate that functionalization of the metal-organic framework Mg2(dobpdc) (dobpdc4- = 4,4?-dioxidobiphenyl-3,3?-dicarboxylate) with the cyclic diamine 2-(aminomethyl)piperidine (2-ampd) produces an adsorbent that is capable of ?90% CO2 capture from a humid natural gas flue emission stream, as confirmed by breakthrough measurements. This material captures CO2 by a cooperative mechanism that enables access to a large CO2 cycling capacity with a small temperature swing (2.4 mmol CO2/g with DeltaT ? 100 C). Significantly, multicomponent adsorption experiments, infrared spectroscopy, magic angle spinning solid-state NMR spectroscopy, and van der Waals-corrected density functional theory studies suggest that water enhances CO2 capture in 2-ampd-Mg2(dobpdc) through hydrogen-bonding interactions with the carbamate groups of the ammonium carbamate chains formed upon CO2 adsorption, thereby increasing the thermodynamic driving force for CO2 binding. In light of the exceptional thermal and oxidative stability of 2-ampd-Mg2(dobpdc), its high CO2 adsorption capacity, and its high CO2 capture rate from a simulated natural gas flue emission stream, this material is one of the most promising adsorbents to date for this important separation.

A series of N-aryl (2a,b) or benzyl (2c,d) substituted piperidoimidazolinium salts and their palladium complexes (3a-d) were prepared and characterized by 1H, 13C NMR, IR spectroscopy and elemental analysis. The crystal structures of 3a and 3c have been determined by X-ray crystallography. Thermogravimetric analysis (TGA) was applied to complexes (3a?d). The palladium complexes have been employed as catalyst for Suzuki-Miyaura cross coupling. The N-aryl substituted complex 3b was a highly efficient precatalyst and successfully employed in Suzuki-Miyaura cross coupling reactions of (hetero)aryl chlorides with arylboronic acids in air. In addition, the oxidative addition step of the reaction mechanism involving chlorobenzene and the catalysts 3a, 3b, 3c and 3d were computationally investigated by the DFT-omega-B97X-D method and complete agreement were obtained with the catalytic results. To measure sigma-donating and pi-acceptor properties of the new ligands, the rhodium carbonyl complexes were also prepared.

A new HPLC method has been developed and validated for determination of enantiomeric purity of 2-piperidinemethanamine within a short run time of less than 10 min. The method was based on pre-column derivation of 2-piperidinemethanamine with 3,5-dinitrobenzoic acid and complete separation of enantiomers has been achieved on a CHI-DMB analytical column (250 mm × 4.6 mm) using n-hexane: ethanol (85:15 v/v) as mobile phase at a flow rate of 1.0 mL min-1 under UV photodiode-array detector detection. Then the effects of mobile phase and temperature on enantioselectivity were further evaluated. The method was validated with respect to precision, accuracy, linearity, limit of detection (LOD), limit of quantification (LOQ) and robustness. The recoveries were between 99.1 and 102.3 % with percentage relative standard deviation less than 1.17 %. The LOD and LOQ for first enantiomer were 13.7 and 46.3 mug mL-1 and for second enantiomer were 15.2 and 51.4 mug mL-1, respectively. This method is expected to be accurate, stable, rapid and sensitive for determination of the enantiomeric purity of 2-piperidinemethanamine in bulk samples. Copyright

Carbon dioxide can be used as a temporary protecting group for amines. A carbamic acid is formed reversibly when CO2 is bubbled through a solution of a sufficiently basic primary amine at room temperature and atmospheric pressure. This reaction is employed for the protection of the amine functionality in several reactions at room temperature where inter- or intramolecular selectivity is desired. The concept is demonstrated for the selective Michael additions to methyl acrylate of a normally less reactive sulfonamide in the presence of a strong amine nucleophile, or of a cyclic secondary amine in the presence of an aliphatic primary amine, or of a beta-ketoester in the presence of amines. The selective acylation of an alcohol in the presence of an amine can be achieved under a CO2 atmosphere as well.

Reversible, Two-Step Single-Crystal to Single-Crystal Phase Transitions between Desloratadine Forms I, II, and III

Single-crystal to single-crystal polymorphic transformations in molecular solids are relatively rare, with changes in crystal structure more commonly leading to destruction of the parent crystal. However, the structural basis for such transitions is of considerable interest given the changes in material properties that can result. The antihistamine desloratadine displays a two-step, reversible single-crystal to single-crystal phase transition during heating/cooling cycles between three conformational polymorphs: the low temperature form I, a polytypic intermediate form II, and the high temperature form III. The two-step transition involves a sequential flipping of the piperidine rings of desloratadine molecules in the crystals, which induce reversible micrometer-scale contraction on heating and expansion on cooling of the largest face of a desloratadine single crystal. Distinct, slow-moving phase boundaries, originating on the (001) face of the crystal, were observed sweeping through the entire crystal in hot-stage microscopy, suggesting a single nucleation event. Computational spectroscopy, using periodic DFT-D phonon calculations, reproduces the experimental variable-temperatureTHz-Raman spectra and rules out the possibility of the phase transformations occurring via any classical soft mode. A combination of variable-temperature powder X-ray diffraction, solid-state NMR, and computational spectroscopy provides a detailed molecular description of the phase transitions, indicating a first-order diffusionless process between I -> II and II -> III, wherein both conformational changes and lattice distortions occur simultaneously in the crystal lattice. The study indicates that a nucleation and growth mechanism is compatible with concerted movements producing a conformational change in organic molecular crystals.

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. you can also check out more blogs about 22990-77-8. Formula: C6H14N2.
