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 ...

The mutual effect of light and organic complexes of Fe(III) on the photodegradation of 3-methylphenol (3MP) was investigated in homogeneous phase. A preliminary study of the organic complex Fe(III)-3MP mixture in the ...

In a first part we studied the chemical composition and biological activities of Pistacia atlantica Desf. and Ferula vesceritensis Coss. & Dur. The GC and GC-MS analyses showed that the essential oils of P. atlantica are ...

This manuscript describes the reductive removal of trityl groups from N-protected tetrazoles, using indium, zinc and arene-catalysed lithiation processes. Chapters 1 and 2 report the development of two efficient processes ...
