Abstract
Ketones are methylenated to form the corresponding olefin by reaction with a bis(alkylchloroalumino)methane, e.g., in the form of its dietherate.
Claims11
A process for the methenylation of the carbonyl oxygen atom of a ketone which comprises reacting the ketone with a bis(alkylchloroaluino)methane to form the corresponding olefin.
A process for the methenylation of the carbonyl oxygen atom of a ketone which comprises reacting the ketone with the dietherate of a bis(alkylchloroalumino)methane, in a molar ration of dietherate to ketone of from about 1.1:1 to about 2:1, to form the corresponding olefin.
