In this work, we focused on improving the description, by theoretical methods DFT type of transition metal complexes, their stability and change of electronic and structural characteristics. For complex Hpca presented ...

The photodegradation of the herbicide phenylurea by using a natural iron oxide (NIO) α-Fe2O3 in aqueous solution at acidic pH has been undertaken. The NIO was characterized by the Raman spectroscopy method. The degradation ...

This work deals with the structural determination and biological evaluation of natural substances isolated from two species of the Lamiaceae family (Salvia aegyptiaca and Saccocalyx satureioides). These family and the genus ...

The subject that we developed "Elaboration of novel catalytic methods for the synthesis of heterocyclic molecules " summarizes: - Through a bibliographical study which puts forward the heterocyclic compounds, the advantage ...

This manuscript includes three main parts: In the first chapter, we described a new method for preparation of 2-aryl-2,3-dihydro-4-quinolonesby the use of the cyclization of the corresponding 2-aminochalconesvia an ...

In the first part of this work, our study was devoted to the phytochemical and biological investigations of the pods of Astragalus armatus ssp. numidicus (Coss. et Dur.) Maire. (Fabaceae). Separation and purification of ...

Our research includes the stady of the phytochemical and biological aspects of the two presented species Bituminaria bituminosa(L.) C.H.Stirton. which belongs to Fabaceae family and Centaurea dimorpha Viv. which belongs ...

In this manuscript, we were interested in the development of the multi-component reactions by the study of the catalytic power of some catalysts on the reaction of Biginelli, the reaction of Hantzsch and the synthesis ...

We prepared, in the first part of our work, the original heterocyclic derivatives by palladiumcatalyzed direct heteroarylation reaction of heteroarenes by chloride derivatives heteroarylsulfonyl. The use of the catalytic ...
