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 the four 5-tert-butyl-2,3,3-trimethylcyclohexanols is reported and the properties of these secondary alcohols are compared with those of the tertiary alcohols obtained earlier from the reduction of 5-tert-butyl-2,3,3-trimethylcyclohexene epoxides. It is confirmed that secondary...
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 convergentsynthesis of the ethyl ended surfactants is based on a one-pot reduction/alkylation of hemifluorinated thioacetate and glucosylated trishydroxymethyl acrylamidomethane (THAM) using NaBH4 in methanol. This "mild" alkylation was studied in order to improve yields and to pass up the use ...

Synthesis and Photochrmic Characteristics of 1,3-Dihydrospiro[2H-indole-2,3′-[3H-]pyrimido[5,4-f][1,4]benzoxazines] and 1,3-Dihydrospiro[2H-indole-2,7′[7H]thiazolo[5,4-f][1,4]benzoxazines]Two new series of 1,3-dihydrospiro[2H-indole-ozazine] derivatives were synthesized, the 1...
A series of compounds (Ia to Id) derived from diethanolamines and bis(N,N dimethylamino) methyl arsane were synthetised. The coordinative bond N As in these molecules makes them “arsatranes”. The physicochemical results all suggest a trigonal bipyramid structure with nitrogen in the apex ...
