Abstract
Preparation of alkenes as well as of cyclopentane and cyclohexane from the corresponding vicinal dichloro and dibromo alkanes and from .alpha.,.omega.-Dichloropentane and .alpha.,.omega.-dibromopentane and .alpha.,.omega.-dichlorohexane and .alpha.,.omega.-dibromohexane respectively, in which these starting compounds are caused to react with with silicon.
Claims7
