Abstract
Procedure for the preparation of oxo compounds. A certain group of tertiary acetylenic carbinols can be isomerized, converting them into the respective alpha, beta-monounsaturated aldehydes, by esterification and consecutive rearrangement under the action of catalytic catalysts of silver or copper, through the respective allenic esters to the aldehydes. When a group of certain (trihydrocarbylsiloxy) vanadium derivatives are used in the catalytic rearrangement of tertiary or secondary acetylenic carbinols, to produce the respective alpha, beta-unsaturated aldehydes or alpha, beta-unsaturated ketones, higher yields can be obtained.
