SYNTHESIS OF OLEFINS FROM KETONES USING BIS(ALKYLCHLOROALUMINO)METHANE ABSTRACT OF THE DISCLOSURE Ketones are methylenated to form the corresponding olefin by reaction with a bis(alkylchloroalumino)methane, e.g., in the form of its dietherate. Examples of ketones which can be methylenated include the cycloalkyl ketones, multi-ring ketones, sterically hindered aliphatic ketones, and aromatic ketones. Yields of from 50-90% can be achieved.
