Nous décrivons la synthèse de bis (alkyl-4 phényl) et bis (alkoxy-4 phényl) tétrathiafulvalènes originaux. Certains d'entre eux présentent un polymorphisme dont on a précisé les températures de transition. We report the synthesis of di(4-alkoxyphenyl)- and di(4-alkanoyloxy-phenyl)...

The synthesis of 2,8-dioxa-6-thiobicyclo[3.2.1]octanes, substituted by alkyl or phenyl groups in positions 1, 4, or 7, is described. Four synthetic routes are compared: (i) action of sodium sulfide on 2,4-dichloro-1,3-dialkyldioxolanes; (ii) action of sodium sulfide on the ...
The silylation of 2-oxa-7,7′-dichloronorcarane has been studied. According to the reagent (Me3SiCl/Li/THF or MeSi3Cl/Mg/HMPT), we observed significant differences in the reactivity, and silyloxabicyclonorcaranes or silylhydrooxepines were obtained. The influence of solvant and experimental ...

The two step preparation of polyphosphazenes-polydichlorophosphazene synthesis and later substitution-allows design of tailor-made structures. For the past few years, a new route to polydichlorophosphazene and a large range of structures have been disclosed leading to many potential applications.Potin,...
