Studies of quinone monooximes and of their metal complexes and synthetic applications by Khadija Omer Badahdah Download PDF EPUB FB2

For some metal complexes of o-quinone monooximes, an analys is of the charge dis- tribution within the o -quinone monooxime ligands through crystallographic data is reported [52]. The syntheses of the title compounds demonstrate a privileged introduction of a nitroso (and a hydroxyl via the Baudisch reaction) group to an aromatic ring.

These complexes first appeared in the literature as early asand a range of applications has subsequently been published.

However, optimisations of the preparative sequences were not considered, and as such, the reactions have Cited by: 1. A simple protocol yielding ortho-substituted nitrosophenols from phenols is demonstrated, in the form of copper(II) bis (nitrosophenolato) complexes.

The developed methodology was applied to a range of substrates, confirming the role of the copper in both the formation and protection of the challenging 1, 2-substitution by: 1.

Studies on metal complexes of ortho-quinone monooximes. Part 9. Analysis of the charge distribution within the o-quinone monooxime ligands through crystallographic data.

The products a and are generated as a result of quinone attachment to different centers of Under similar conditions an analogous compound, 10,dimethyl-9,10,trihydro[1,2-b]oxonino[4,5- b ]quinoxalineone b was isolated from and 1,2-naphthoquinone b (TL67).

Synthetic Applications of Nonmetal Catalysts for Homogeneous Oxidations Waldemar Adam, Chantu R. Saha-Möller, and Pralhad A. Ganeshpure Chemical Reviews (11), Cited by: Oscar Varela, in Advances in Carbohydrate Chemistry and Biochemistry, 12 M iscellaneous O xidants Transition-Metal Cations.

Oxidation of aldoses and ketoses with ferricyanide under alkaline conditions involves the 1,2-enediol as an intermediate.

Such an oxidation has been previously described in detail (Ref. 1, p. ).A number of studies on the kinetics of oxidation of sugars with.

Whereas the predecessor mainly covered the limitations of aliphatic substitution reactions, this new volume focuses on the most important aromatic substitution reactions, both electrophilic and nucleophilic, such as amination reactions, halogenation reactions, Friedel-Crafts acylations, or transition metal-catalyzed arylation reactions.

In the research team of Doctor of Chemical Sciences, Professor A.F. Khlebnikov research is carried out on the synthesis, investigation of the chemistry, and synthetic applications of azirines [––] and aziridines [–], whose high reactivity is due to the ring strain, and also of.

Both types of superelectrophiles and their chemistry will be discussed in subsequent chapters. Theoretical calculations have been done on varied superelctrophilic species. They are often found in deep potential energy wells on the energy surfaces, although others are higher lying minima.
