Abstract
A method for preparing ketones has advantages of improving yields and reducing the time of the reactions due to high efficiency of catalysts. Ketones are prepared by reacting an aliphatic or an aromatic aldehyde with a vinyl olefin having an aliphatic or aromatic alkyl moiety in the presence of a transition metal catalyst, 2-aminopyridine catalyst, a primary amine and an acid, as catalysts and additives.
