    公开(公告)日:1981-03-24
    Compounds containing at least one keto group and at least one peroxy group, each peroxy oxygen being joined to a tertiary carbon atom. Examples: 2-Methyl-2-(t-butylperoxy)-4-pentanone. 2,6-Dimethyl-2,6-bis(t-butylperoxy)-4-heptanone. 3,5,5-Trimethyl-3-(t-butylperoxy)cyclohexanone. The compounds are prepared by the strong acid catalyzed addition of a tertiary hydroperoxide to an .alpha.,.beta.-unsaturated ketone. Illustration: Mesityl oxide and pinanyl hydroperoxide, in slight excess, were reacted at 0.degree. C. in the presence of 77% sulfuric acid; the reaction mix was stirred for 16 hours at 25.degree. C. Product 2-methyl-2-pinanylperoxy-4-pentanone was recovered.
