Polymeric -peroxides (3) from hydrogen peroxide and lower carbon ketones have been separated by paper or column chromatography and have been characterized by conversion to the bis(p-(nitro)peroxybenzoates). Oligomeric peroxides (3, R = methyl, R = ethyl, n = 1-4) from methyl ethyl ketone have been separated and interconverted by suitable treatment with ketone and hydrogen peroxide (44). [Pg.116]

It is possible to introduce this group selectively onto a primary alcohol in the presence of a secondary alcohol. The derivative is stable to KMn04, w-chloro-peroxybenzoic acid, LiAlH4, and Cr03 Pyr. Since this derivative is similar to the p-methoxyphenyl ether it should also be possible to remove it oxidatively. The GUM ethers are less stable than the MEM ethers in acid but have stability comparable to that of tlie SEM ethers. It is possible to remove the GUM ether in the presence of a MEM ether. [Pg.25]

Free radical initiators can polymerize olefmic compounds. These chemical compounds have a weak covalent bond that breaks easily into two free radicals when subjected to heat. Peroxides, hydroperoxides and azo compounds are commonly used. For example, heating peroxybenzoic acid forms two free radicals, which can initiate the polymerization reaction ... [Pg.305]

The chemistry of peroxyesters (38) also commonly called pcrcsters has been reviewed by Sawaki,199 Bouillion el al.m and Singer.194 The peroxyesters are sources of alkoxy and acyloxy radicals (Scheme 3.32). Most commonly encountered peroxyesters are derivatives of /-alkyl hydroperoxides (< .g. /-butyl peroxybenzoate, BPB). [Pg.88]

The reactions of arenediazonium ions with 7V-alkyl- or 7V-arylhydroxylamines were investigated by Bamberger (1920b, and earlier papers). Mitsuhashi et al. (1965) showed that the l,3-diaryl-3-hydroxytriazenes are tautomeric with 1,3-diaryltriazene-3-oxides (Scheme 6-16). Oxidation of 1,3-diaryltriazenes with peroxybenzoic acid in ether yields the same product as that from diazonium salts and TV-arylhydroxyl-amine. The infrared spectrum of the product obtained by coupling diazotized relabeled aniline with A/-phenylhydroxylamine indicates that the diaryltriazene-oxide is the preponderant tautomer. [Pg.121]

The solution is stirred for an additional 2 hours and is then cooled to 15°. Fifty grams of chopped ice and 75 ml. of ice-cold saturated ammonium sulfate solution are cautiously added in sequence while the temperature is maintained below 25° during the dilution (Note 4). The contents of the beaker are transferred to a separatory funnel, and the peroxybenzoic acid solution is... [Pg.93]
