The species present in solutions of [12]crown-4, [15]crown-5, and [18]crown-6 complexes with BeCl2 were investigated by 1H, 13C, and 9Be NMR spectroscopy. These are [(BeCl)([12]crown-4)]+ (1), [(BeCl2)([15]crown-5)] (2), and [(BeCl2)2([18]crown-6)] (3), however in solution the majority of the crown ethers is not bound to beryllium. In case of [12]crown-4 and [18]crown-6 huge amounts of precipitate are formed, which were identified to be [(BeCl)([12]crown-4)]Cl (1a) and compound 3, while [15]crown-5 is capable of dissolving more than one equivalent of BeCl2 in dichloromethane.

left bracket Y(NO//3)//2(OH//2)//5 right bracket left bracket NO//3 right bracket multiplied by (times) 2(15-crown-5) was prepared by the addition of 15-crown-5, dissolved in a 1:3 solution of CH//3OH:CH//3CN, to a solution of Y(NO//3)//3 multiplied by (times) nH//2O in the same solvent mixture. The crystal and molecular structures of the title compounds were determined by single-crystal x-ray diffraction using counter methods with crystals obtained by slowly cooling the reaction mixture. The complex is monoclinic. High thermal motion and disorder were encountered when refining the two crown-ether molecules and the uncoordinated nitrate group.

Lithium-7 NMR spectrometry was used to study the complexation reaction between lithium ions and several 12-, 15- and 18-membered crown ethers in a number of binary acetonitrile-nitrobenzene mixtures. Formation constants of the resulting 1:1 complexes in different solvent mixtures were determined by computer fitting of the chemical shift-mole ratio data. There is an inverse relationship between the complex stability and the amount of acetonitrile in the mixed solvent. Among different sized crown ethers used, 15-crowns were found to form the most stable Li+ complexes in the series. The influence of substitution on the macrocyclic rings on the stability of the resulting complexes is discussed.

Rate enhancements for the reduction of dioxygen by a MnII complex were observed in the presence of redox-inactive group 2 metal ions. The rate changes were correlated with an increase in the Lewis acidity of the group 2 metal ions. These studies led to the isolation of heterobimetallic complexes containing MnIII-(mu-OH)-MII cores (MII = CaII, BaII) in which the hydroxo oxygen atom is derived from O2. This type of core structure has relevance to the oxygen-evolving complex within photosystem II.

The complex formation between different crown ethers and the cryptand [222] with alkali metal and ammonium ions in chloroform has been investigated by means of calorimetric titrations. The stability constants, reaction enthalpies and entropies for complex formation in chloroform have been determined. The complexation of alkali metal ions is favored by enthalpic contributions and influenced by both the ligand and the nature of the cation. The reaction enthalpies for complex formation of different ammonium salts with cryptand [222] are higher compared to the corresponding values for the reaction with different 18-crown-6 derivatives in chloroform due to the complete encapsulation of ammonium ion by the cryptand [222]. The benzo group attached to the crown ethers and the nature of the anion borne by the ammonium ion influence complex formation of ammonium with crown ethers. In the case of ammonium salts, competitive measurements have been carried out to underline the influence of the anion upon the complex formation. From the reaction enthalpies for complexation of ammonium ions, the contributions for the formation of hydrogen bonds are calculated using experimental data.

1H NMR spectroscopy was used to investigate the stoichiometry and stability of the drug ketamine cation complexes with some crown ethers, such as 15-crown-5 (15C5), aza-15-crown-5 (A15C5), 18-crown-6 (18C6), aza-18-crown-6 (A18C6), diaza-18-crown-6 (DA18C6), dibenzyl-diaza-18-crown-6 (DBzDA18C6) and cryptant [2,2,2] (C222) in acetonitrile (AN), dimethylsulfoxide (DMSO) and methanol (MeOH) at 27 C. In order to evaluate the formation constants of the ketamine cation complexes, the CH3 protons chemical shift (on the nitrogen atom of ketamine) was measured as function of ligand/ketamine mole ratio. The formation constant of resulting complexes were calculated by the computer fitting of chemical shift versus mole ratio data to appropriate equations. A significant chemical shift variation was not observed for 15C5 and 18C6. The stoichiometry of the mono aza and diaza ligands are 1:1 and 1:2 (ligand/ketamine), respectively. In all of the solvents studied, DA18C6 formed more stable complexes than other ligands. The solvent effect on the stability of these complexes is discussed.

In the present study, the biomass was converted into liquid and solid residues by using hydrothermal liquefaction method at 250, 300 and 350 C with (FeCl3, NaOH) and without catalyst. The resultant products were examined using GC?MS, FT-IR, 1H NMR, SEM, and elemental analysis methods. According to the performed analyses, the highest liquid product yield (total bio-oil) was found to be 38.08% at 300 C by using FeCl3 as catalyst. In the experiments carried out at 350 C, the highest HHV value was found to be 32.35 MJ kg?1 by using NaOH catalyst. The energy values of products obtained at the end of experiments were compared to the values obtained from pyrolysis and supercritical liquefaction method, and it was determined that the liquid products having higher level of energy value were achieved by using hydrothermal liquefaction method.
