    Abstract: 1,258,963. Trimethyl - 2 - cyclohexen -1 -ones. BADISCHE ANILIN- & SODA-FABRIK A.G. 7 March, 1969 [8 March, 1968; 26 July, 1968], No. 12117/69. Heading C2C. In a process for the production of a trimethyl - 2 - cyclohexen - 1 - one diethyl ketone is reacted in the presence of a basic reagent either (a) with crotonaldehyde or a compound which in the presence of a basic reagent is converted into crotonaldehyde, thereby yielding 2,5,6 - trimethyl - 2 - cyclohexen - 1 - one, or (b) with methyl vinyl ketone or a compound which in the presence of a basic reagent is converted into methyl vinyl ketone, thereby yielding 2,3,6 - trimethyl - 2 - cyclohexen- 1-one. 4 - Methyl - 3 - ethyl - 2 - cyclohexen- 1-one formed as a by-product is isomerized to 2,3,6 - trimethyl - 2 - cyclohexen - 1 - one by treatment with an aqueous base. 2,3,6 - Trimethylphenol is obtained by dehydrogenation of either 2,5,6- or 2,3,6-trimethyl-2-cyclohexen- 1-one produced by the above processes. The dehydrogenation is carried out by heating the cyclohexenones with sulphur, selenium or chloranil or in the presence of metals such as iron, cobalt, nickel, rhodium, platinum, palladium, copper and silver. Numerous compounds are specified which form crotonaldehyde or methyl vinyl ketone in the presence of a basic reagent.
