Abstract
A multi-stage synthesis is effective for preparing 1-olefins from aldehydes. The aldehyde is condensed with acetone to form an &agr;,&bgr;-unsaturated ketone. The unsaturated ketone is hydrogenated to yield a saturated alcohol. By dehydrating the saturated alcohol a 1-olefin is obtained. The olefin can be isolated in high yield and purified.
