A special type of polymeric antioxidant is anoxomer, which consists of 1,4-benzenediol, 2-(l,l-dimethylethyl)-polymer with diethylbenzene, 4-(l,l-dimethyl-ethyl)phenol, 4-methoxy-phenol, 4,4 -(l-methylethylidene)bis(phenol), and 4-methylphenol prepared by condensation polymerization of divinylbenzene (m- and p-) with tert-butylhydroquinone, tert-butylphenol, hy-droxyanisole, p-cresol, and 4,4 -isopropylidenediphenol. Total monomers, dimers, and trimers below 500 are not more than 1%. Anoxomer is permitted in the United States as an antioxidant in food at a level of not more than 5 ppm of fat and oil content of the food. 

Alkenyl carbene complex was dissolved in benzene at a concentration of 0.002 M. The red solution was deoxygenated by the freeze-pump-thaw method (four cycles) and heated in an oil bath to 100°C. The solution turned from red to yellow during the reaction. After the completion of the reaction, the solvent was removed, and the residue was taken up in CH2Cl2/ether, and stirred in air overnight. The mixture was then loaded on silica gel and chromatographed to give 40% of p-methoxy phenol derivative and 21% of m-methoxy phenol derivative.

Alcohols and Phenols.— The discovery of a convenient preparation of 3-methoxy-4-isopropylbenzyl alcohol has resulted from a systematic study s concerned with the preferential oxidation of methyl groups attached to aromatic rings. This showed that the oxidation of aromatic compounds of low ionisation potential with Pb(OAc)4 can lead to selective oxidation of Me in preference to Pr. m-Methoxy-p-cymene (25), for example, can be converted into 4-isopropyl-3-methoxybenzyl acetate (26).

Corypalline, CnHijOjN (Corydalis spp. Nos. 9, 22 list, p. 170). This phenolic base, m.p. 168°, picrate, m.p. 178°, contains one methoxyl group and on methylation yields 2-methyl-6 7-dimethoxytetrahydrof5oquinoline, Ci2Hi,02N, m.p. 82°, and on ethylation, 2-methyl-6-methoxy-7-ethoxy-tetrahydrofsoquinoline, m.p. 65°, whence the free hydroxyl appears to be at C and this has been confirmed by the synthesis of corypalline by a method analogous with that used by Spath, Orekhov and Kuffner. Corypalline is therefore hydrohydrastinine (XII) with the methylenedioxy group replaced by MeO at C and. OH at C (Manske). ... 

S. Henningsii (S. Africa). Two crystalline alkaloids (1) 23 28 5 2> m.p. 280-5-282°, [a]], ° — 80° (EtOH) contains one methoxyl, but no methylimino group and is possibly phenolic (2) 24 3305 2> m.p. 214-5-215°, contains two methoxyl groups and gives a violet coloration with Frohde s reagent. The alkaloids are possibly mono-and di-methoxy derivatives of the same parent base. Amorphous alkaloids are also present and possibly a third crystalline base (Rindl, S, Afr. J. Sci., 1929, 26, 50 Trans. Boy. Soc. S, Africa, 1931, 20, 59 (with Sapiro), ibid., 1936, 23, 361).
