Abstract
Process for the preparation of unsaturated ketones, which comprises reacting a 1,1-disubstituted propargyl alcohol with a ketal represented by the general formula ** (See formula) ** or an enol ether represented by the general formula ** (See formula) ** wherein R1 represents a member selected from the group consisting of hydrogen, lower alkenyl and lower alkyl radicals, R2 and R3 represent a lower alkyl radical and R1 and R2 taken together represent a polymethylene bridge, in the presence of an acid condensing agent and, if desired, isomerizing the reaction product.
