Complexation of Constrained Ligands Piperazine, N-substituted Piperazines, and Thiomorpholine

Complexation of the symmetric cyclic diamine piperazine (1,4-diazacyclohexane) has been examined in dry dimethyl formamide by spectrophotometric titrations (with Cu2+, Ni2+) to define formation constants, and by stopped-flow kinetics to define the complexation rates and reaction pathway. Initial formation of a rarely observed eta(1)-piperazine intermediate occurs in a rapid second-order reactions. This intermediate then undergoes two competing reactions: formation of (chelated) eta(2)-piperazine (ML) or the formation of (bridging) mu-piperazine (in M2L and M2L3, speciation depending on relative concentrations). Protonation constants and formation constants for complexation in water of N-ethylpiperazine and thiomorpholine (1-aza-4-thiocyclohexane, tm) have been determined by potentiometric titration; 1:1 complexes with first-row M2+ display a log K from similar to 4 to 6, with speciation that suggests chelation of the heterocycles may be involved. Complexation of thiomorpholine has been further probed by the synthesis of Pd-II complexes. The N-monodentate coordination mode has been confirmed in trans-[Pd(tm)(2)Br-2] by an X-ray crystal structure. Complexation of N-(2-aminoethyl)piperazine to Cu-II as a bidentate ligand involving the primary and tertiary amines is also defined by an X-ray crystal structure.

Enhancers were applied at 0.4 M in propylene glycol (PG) (or as a suspension) to mouse skin. Hydrocortisone (0.03 M in PG) was applied 1 h following enhancer treatment. Controls (no pretreatment) yielded 24 h diffusion cell receptor concentrations (Q(24)) of 9.93 +/- 3.15 mu M and model drug skin retention of 26.1 +/- 5.6 mu g g(-1). Compound 7 yielded a high Q(24) of 208.18 +/- 39.52 mu M. The highest skin retention was observed with 6 of 566.7 +/- 39.7 mu g g(-1). Azone gave values of 218.96 +/- 47.84 mu M for Q(24) and 294.9 +/- 66.7 mu g g(-1) for skin retention. Compounds 13 and 14 gave Q(24) values of 274.44 +/- 50.90 and 220.21 +/- 59.63 mu M and skin retention values of 226.5 +/- 51.8 and 259.0 +/- 62.2 mu g g(-1), respectively.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. A catalyst, therefore, does not appear in the overall stoichiometry of the reaction it catalyzes.I hope my blog about 766-97-2 is helpful to your research. Recommanded Product: 766-97-2.

Natural abundance nitrogen-15 nuclear magnetic resonance spectral studies on selected donors

The natural abundance N-15-NMR chemical shifts of selected aliphatic amines, 2-substituted pyridine type compounds, bialicyclic tertiary amines have been measured as a function of the nature of the solvent. In the case of cyclic aliphatic amines, like piperidine, morpholine, piperazine, thiomorpholine, the nitrogen is more shielded in concentrated solution compared to that in dilute solution whereas in the hydrogen bonding and protonating solvents there is a prominent deshielding. 2-Substituted pyridines studied can be further divided into four sub groups. The site of hydrogen bonding and protonation in 2-amino, 2-hydroxy and 2-mercapto pyridines have been conclusively proved from the N-15-NMR chemical shifts and the well-known tautomeric forms of the above compounds. Similarly in the case of 2-(2-thienyl)pyridine and 2-(3-thienyl)pyridine, the site of donation has been proved as the nitrogen of the pyridine ring in both the compounds. In a similar manner, the site of hydrogen bonding and protonation in two individual compounds 2-anilinopyridine and 2-(2-pyridyl)benzimidazole have also been established. Among the bialicyclic amines, 1,2-diazabicyclo[2.2.2]octane (DABCO) behaved differently from the other two compounds. In both 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and 1,5-diazabicyclo[4.3.0]non-5-ene (DBN), it was possible to show that N-1-nitrogen in both the compounds is the site of donation. The effect of the second donor site on the N-15-NMR chemical shift, the site of donation in the selected compounds and some typical compounds reported in literature have been presented and discussed.

Energetics and Reactivity of Morpholine and Thiomorpholine: A Joint Experimental and Computational Study

The influence of the heteroatoms in the conformational, energetic, and reactivity trends exhibited by morpholine and thiomorpholine isosteres was obtained from computational and experimental thermochemical studies. For those purposes, the gas-phase standard (p = 0.1 MPa) molar enthalpies of formation of the compounds, at T = 298.15 K, were determined from the experimental values of the standard molar. enthalpies of formation, in the liquid phase, and of the standard molar: enthalpies of vaporization, obtained by calorimetric techniques, and also from composite G3(MP2)// B3LYP calculations making use of appropriate working reactions. A very good agreement was found between the calculated and the experimental gas-phase enthalpies of formation. The computational study was further extended to the calculation of other gas-phase thermodynamic properties these compounds, namely, the N-H or C-H bond dissociation enthalpies, gas-phase acidities and basicitics, proton affinities and adiabatic ionization enthalpies, and the energies and structures of the conformational stereoisomers of morpholine and thiomorpholine.
