Abstract
The present invention relates to a general synthesis for producing secondaryalkoxy-1-alkenes in commercial quantities in good yields by reacting cyclic and acyclic ketones and the corresponding alcohol with a secondary alkyl orthoformate ester in the presence of an acid catalyst, a Lewis acid, ferric chloride being preferred, and recovering the produce as a liquid of high purity.
