The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[Tc(NO)Cl(4)] with Di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO)Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl(2)(HOMe)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(...

In the title compound, [(Ph(3)P)(2)N](+)·[Cl-H-Cl](-) or C(36)H(30)NP(2) (+)·Cl(2)H(-), the H atom of the [Cl-H-Cl](-) anion and the N atom of the [(Ph(3)P)(2)N](+) cation are located on a twofold axis, yielding overall symmetry 2 for both the cation and the anion. The central P-N-P angle [144.12 (13)°] of the cation is in the expected range and indicates only weak cation-anion inter-actions. T...

in order to evaluate the effect of berberis vulgaris extract on the experimental ulcers of cutaneous leishmaniasis (cl) on balb/c mice, a study was undertaken over a 12 months period. forty balb/c mice were divided into 2 main groups a and b. each main group in turn was divided into 5 sub groups of 4 mice and each sub group were inoculated subcutaneously by 0.1ml liquid phase culture containing...

3-Carboxy-1-sulfopyridin-1-ium chloride ([CPySO3H]+Cl-) as a novel ionic organocatalyst for thecondensation of aldehydes and 2-methylindole to synthesize bis(2-methyl-1H-indole) derivatives inacetonitrile at room temperature has been developed. Some tetrakis (2-methyl-1H-indole)derivatives have also been synthesized by the reaction of 2,2'-(butane-1,4-diylbis(oxy))dibenzaldehyde and 2-methylind...

smooth coefficients aα(x), L+ be a formally adjoint differential operation. Let L0, L0 be minimal operators (i.e., for example, D(L0) is the clozure of C∞ 0 (Ω) in the norm of the graph ‖u‖L = ‖u‖L2(Ω)+‖Lu‖L2(Ω)), and L, L+ be maximal expansions of L,L+ in the space L2(Ω) respectively (i.e. L = (L0 ) ∗, L+ = (L0)∗), L̃ = L|D(L̃) where D(L̃) is the clozure of C∞(Ω̄) in the norm of the graph ‖u‖L and...
