Abstract

1,239,801. Unsaturated ketones. BADISCHE ANILIN- & SODA-FABRIK A.G. 15 Nov., 1968 [17 Nov., 1967], No. 54206/68. Heading C2C. Alk - 1 - en - 6 - ones and cyclized analogues thereof in which pairs of valencies are linked to form rings are prepared by heating alk-l-en- 4-ols or cyclized analogues thereof at 100- 400‹ C. with a ketone which bears at least one hydrogen atom on a carbon atom adjacent to the carbonyl group. Examples prepare 2- methylhept - 1 - en - 6 - one from acetone and 2 - methylbut - 1 - en - 4 - ol, hept - 1 - en - 6- one from acetone and but - 1 - en - 4 - ol, and 2,5 - dimethyloct - 1 - en - 6 - one from diethyl ketone and 2 - methylbut - 1 - en - 4 - ol.
