The reaction between iodo and N-methyl-piperazine or thiomorpholine in water, in the presence of KI, led to the formation of stable and easy to handle amine-iodine complexes, as the complex morpholine-iodo previously reported in the literature. However, the complex obtained using N,N-tetrametylethylenediamine proved less stable, while no complex was formed when piperidine was used as base. These results show that the presence of a second heteroatom in the structure of amines is of fundamental importance for the formation and stability of these complexes. In this work we describe, for the first time, the use of complexes morpholine-iodo, N-methyl-piperazine-iodo and thiomorpholine-iodo as iodinating reagents of several substituted phenols, leading to iodinated products in good to excellent yields.

Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.Welcome to check out more blogs about 72235-52-0, in my other articles. Electric Literature of 72235-52-0.

Carbamate formation is one of the major chemical reactions that can occur in solution in the capture of CO2 by amine-based solvents, and carbamate formation makes a significant enthalpy contribution to the absorption-desorption of CO2 that occurs in the absorber/stripper columns of the PCC process. Consequently, the formation of carbamates of selected series of primary and secondary amines over the temperature range (288 to 318) K has been investigated by equilibrium H-1 NMR studies, and the stability constants (K-9) for the equilibrium: RNH2 + HCO3- reversible arrow(K9) RNHCOO- + H2O are reported. van’t Hoff analyses have resulted in standard molar enthalpies, Delta H-m(o), and entropies, Delta S-m(o), of carbamate formation. A Delta H-m(o) – Delta S-m(o) plot generates a linear correlation for carbamate formation (providing a mean standard molar free energy, Delta G(m)(o), for carbamate formation of about -7 kJ . mol (1)), and this relationship helps provide a guide to the selection of an amine(s) solvent for CO2 capture, in terms of enthalpy considerations. A linear Delta H-m(o) – Delta S-m(o) plot also occurs for carbamate protonation. The formation of the carbamates has been correlated with systematic changes in composition and structure, and steric effects have been identified by comparing molecular geometries obtained using density functional B3LYP/6-311++G(d,p) calculations. Trends in steric effects have been identified in the series of compounds monoethanolamine (MEA), 1-amino-2-propanol, 2-amino-1-propanol (AP) and 2-amino-2-methyl-1-propanol (AMP). In the case of 2-piperidinemethanol, 2-piperidineethanol and 3-piperidinemethanol, strong intramolecular hydrogen bonding is shown to be the likely cause for lack of carbamate formation, and in the ring systems of pyrrolidine, morpholine, piperidine and thiomorpholine trends in carbamate formation (as given by K-9) have been correlated with the internal ring angle at the amine nitrogen, as well as the planarity of the environment around the nitrogen atom.

Donor Abilities of Heterocyclic Neutral Lewis Bases in a Nickel(II) Salicylaldehyde 4-Phenylthiosemicarbazonato Coordination Environment

Eight mononuclear [Ni(sal 4-Phtsc)center dot D] thiosemicarbazonato complexes [sal4-Phtsc = salicylaldehyde 4-phenylthiosemicarbazonato ligand; D = imidazole (1), methylimidazole (2), pyridine (3), 4-aminopyridine (4), 4-methylpyridine (6), morpholine (7), thiomorpholine (8), 2-aminophenol (9)] and one dinuclear {[Ni(sal 4-Phtsc)](2)center dot D} center dot 2DMSO [D = 4,4′-bipyridine (5)] complex have been prepared by adding the corresponding Lewis base to the methanol suspension of the parent complex [Ni(sal 4-Phtsc)(H(2)sal4-Phtsc)]center dot CH3OH. The exchange of the neutral salicylaldehyde 4-phenylthiosemicarbazone (H(2)sal4-Phtsc) ligand in the parent complex for the appropriate Lewis base has been confirmed by IR spectroscopy and powder X-ray diffraction (PXRD) in the solid state. The single-crystal X-ray diffraction of seven complexes 1 and 3-8 confirmed the formation of the complexes with the Ni-II ion, coordinated through O,N,S-donor atoms from the dibasic salicylaldehyde 4-phenylthiosemicarbazonato ligand and endocyclic N-donor atom from the neutral ligand D in the form of a distorted square-planar coordination. NMR spectroscopy in DMF or DMSO and quantum mechanical calculations have been performed in order to explain and compare the stability of the complexes in solution, depending on the polarity of solvents in the context of donor properties and the nucleophilicity of the heterocyclic Lewis base. The single-crystal X-ray data enables a comparison with calculated standard Gibbs energies of binding in the context of crystal packing forces, leading to a general conclusion that the stability of the mononuclear complexes results in the formation of more stable hydrogen-bonded cyclic dimers as a crystal packing pattern.

2-Thiomorpholino-5-Aryl-6H-1,3,4-Thiadiazine Hydrobromides and Their Ability to Inhibit Nonenzymatic Protein Glycosylation

Cyclocondensation of alpha-halogenacetophenones with an original 4-morpholine thiosemicarbazide was used to synthesize a group of new Captions: of the 1,3,4-thiadiazine group, containing a thiomorpholine fragment at position 2 of the thiadiazine ring. Two members of this group of compounds were found to produce effective inhibition of nonenzymatic protein glycosylation in an in vitro model system. These test results allow compounds containing phenyl and fluorophenyl fragments IIIa and IIIb to be recommended for further study in in vivo experiments.

Nitrosation of 2-hydroxyethylpiperidine

The kinetics of the nitrosation of 2-hydroxyethylpiperidine have been studied in acidic (0.05-0.30 mol dm(-3) HClO4) aqueous media. The reaction rate is first order with respect to nitrite and amine and independent of acidity and shows an experimental isotope effect of 1.73. The most plausible mechanism involves the fast formation of an alkyl nitrite in the protonated amine (equilibrium constant estimated as 0.014 dm(3) mol(-1)). The loss of a proton from this intermediate is the rate-limiting step, and it is followed by a fast internal nitroso group transfer from the oxygen to the nitrogen atom to give the corresponding N-nitroso compound. A comparison of this nitrosation pathway of secondary amines in acid media with the nitrosation of thiomorpholine and piperidine, and with that of amines by alkyl nitrites in basic media is also discussed.
