Reaction of Co(II)bleomycin with dioxygen.
The reaction of Co(II)bleomycin with dioxygen has been investigated. Dioxygen binds to the Co(II) complex within the time of mixing according to electron spin resonance and uv-visible spectroscopy and dioxygen analysis. Then, two dioxygenated cobalt centers react, releasing 1 mol of O2 and forming an intermediate characterized by a few highly shifted 1H NMR resonances and loss of the ESR spectr...
متن کاملMonoterpenes of Salvia leucophylla
The " Salvia phenomenon" is one of the most famous examples of allelopathic interaction between higher plants. The Salvia thickets are surrounded by zones of bare soil ("bare zone", 1-3 m in width), which merge into areas of inhibited grassland ("zone of inhibition") and finally undisturbed grassland at a distance of 3-9 m. This characteristic vegetation pattern was attributed to monoterpenes, ...
متن کاملUnsaturated aldehydes as alkene equivalents in the Diels-Alder reaction.
A one-pot procedure is described for using alpha,beta-unsaturated aldehydes as olefin equivalents in the Diels-Alder reaction. The method combines the normal electron demand cycloaddition with aldehyde dienophiles and the rhodium-catalyzed decarbonylation of aldehydes to afford cyclohexenes with no electron-withdrawing substituents. In this way, the aldehyde group serves as a traceless control ...
متن کاملEnantioselective synthesis of functionalized pyrazoles by NHC-catalyzed reaction of pyrazolones with α,β-unsaturated aldehydes.
The N-heterocyclic carbene (NHC)-organocatalyzed enantioselective annulation reaction of pyrazolones with α,β-unsaturated aldehydes proceeding via the chiral α,β-unsaturated acyl azolium intermediates under oxidative conditions is presented. The reaction afforded dihydropyranone-fused pyrazoles in moderate to good yields and good er values under operationally simple and base-free conditions.
متن کاملNumerical Methods for Di usion - Reaction - Transport Processes in Unsaturated
This paper introduces a new grid reenement and coarsening technique for the approximation of partial diierential equations including a rst order time derivative. This hierarchical movement algorithm is based on the nested iteration method. The combination of this algorithm, a quasi Newton method and the Schur-complement multi-grid method leads to an eecient method for the solution of partial di...
