Abstract
1290785 Isomerizing unsaturated ketones BADISCHE ANILIN- & SODA-FABRIK AG 27 Feb 1970 [1 March 1969] 9509/70 Heading C2C Alk-2-enones are prepared by isomerizing corresponding alk-1-enones at 0-250‹ C. in the presence of a finely divided metal of Group VIII or a palladous compound and in the presence of H 2 . In examples 2-methylhept-2-en- 6-one is obtained from 2-methylhept-1-en-6-one and 2,3-dimethylhept-2-en-6-one from 2,3-dimethylbept-1-en-6-one.
