Some 2-halo-(1-methyl-1H-imidazole) derivatives were prepared by selective halogenation reaction (bromination, chlorination and iodination). The addition of -bromoacetophenone to 2-bromo(chloro)-1-methyl-1H-imidazole ...

This manuscript encloses three principal parts: the first part, we have described the synthesis of tetrazoles which are a class of heterocycles with a wide range of applications in medicinal chemistry and in material ...

This thesis describes a density functional theory (DFT) studies of electronic structures of real and hypothetical boranes, heteroboranes and metalaheteroboranes clusters, by the use of B3LYP functional, 6-311++G(d,p) basis ...

The present works concern two plants of Sedum genus (Crassulaceae) : S. caeruleum and S. pubescens. The extraction and chromatographic separations (CC, TLC) of the chloroform, ethylacetate, and n-butanol extracts of S. ...

In general, The search for new natural products with therapeutic properties as one of the main objectives for researchers, in this context we have begun to study phytochemical and biological Algerian medicinal plant which ...

The subject of this work concerns the phytochemical study of Cachrys libanotis L. from east Algeria, species of the Apiaceae family. Isolation and purification of compounds from aerial parts of Cachrys libanotis L. were ...

The work presented in this thesis is devoted to the study of the electronic structure and physical properties of charge-transfer salts. Different theoretical methods (EHT, DFT, TD-DFT, MP2 ...) were used, with suitable ...
