Silylation de dérivés gem-dihalogénés bicycliques: synthèse de dihydro- et tétrahydro-oxépines siliciées
The silylation of 2-oxa-7,7′-dichloronorcarane has been studied. According to the reagent (Me 3 SiCl/Li/THF or MeSi 3 Cl/Mg/HMPT), we observed significant differences in the reactivity, and silyloxabicyclonorcaranes or silylhydrooxepines were obtained. The influence of solvant and experimental condi...
