CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
English6-Alkoxy-7-chloro-7,7-difluoro-5- [ (S)-(4-methylphenyl)sulfinyl]-I $heptadieneshave been transformed, through chlorine atom abstraction by tributyltin radical, into the corresponding difluoroallyl radicals, which, via intramolecular trapping by the vinyl group and reduction of the cyclohexenylmethyl and cycloheptenyl radicals obtained, gave gem-difluoro-cyclohexene and -cycloheptene derivatives. Reduction of the intermediate difluoroallyl radical afforded the corresponding dechlorinated open-chain difluoro compounds as side-products.
