Description
med 2-methyl-butan-3-on med formlen
(III) i nærværelse af hydrogenhalogenidsyrer, halogenerer de herved dannede 4,4-dimethyl-3-halogen-l-hexen-5-oner med den almene formel
i hvilken Hal betyder chlor eller brom, og omsætter de derved dannede forbindelser med den almene formel
(V) med baser med den almene formel
(VI) i hvilken M betegner et ækvivalent af en alkali- eller jord-alkalimetalion.
4,4-Dimethyl-3-halogen-l-hexen-5-onerne med den almene formel IV kan fremstilles ved, at aldehyder med den almene formel II omsættes med 2-methyl-butan-3-on med formlen III i nærværelse af hydrogenhalogenider.
Forbindelser med formlen V fremstilles ved, at 4,4-dimethyl--3-halogen-l-hexen-5-oner med formlen IV halogeneres.
