Contribution à la valorisation des goudrons de houille : le carbazole une voie vers l'indole ? : alkylation réductrice des brais et de substances modèles

Abstract : In the way to valorize the products of coal cokefaction : 2 types of compounds have been studied. In the first, different ways of the transformation of carbazole into indole have been tried. Direct oxidation of the carbazole system or smooth reduction of one aromatic ring followed by oxidation of the reduced system were the methods used. The second part is devoted to the study of cokefaction pitch by reductive alkylation. The methods used for determination of pitche structure has benn apllied to model compounds especially heterocyclic systems like carbazole, dibenzothiophene, acridine etc..By this way we could show the behaviour of these compounds under reduction or alkylation conditions which are competitive in the Birch type reduction we have employed to do the study
