The role of sulphydryl groups of yeast carboxylase

“…The following have been used (in parentheses are given the source or method of preparation): methyldichloroarsine (Baeyer, 1898) b.p. 132-134°; 3-amino-4hydroxyphenylarsenoxide hydrochloride (Parke Davis and Co.), 3-amino-4-hydroxyphenyldichloroarsine hydrochloride (E. R. Squibb and Sons); p-chloromercuribenzoic acid (Whitmore & Woodward, 1941) 99.5% pure, as determined by chlorine estimation; L-cystine (E. Merck, Darmstadt); iodoacetic acid (Schering-Kahlbaum); ethyl iodoacetate (Tiemann, 1898); chloroacetophenone and bromobenzyl cyanide (Rojahn & Giral, 1946); o-iodosobenzoic acid (Askenasy & Meyer, 1893), 99.5% pure by iodometric titration; alloxan (Eastman-Kodak Co.); DL-cysteine hydrochloride, and glutathione (Eastman-Kodak Co.); 2:3-dimercaptopropanol (Boots Pure Drug Co., Ltd.); cocarboxylase (Hoffman-La Roche) and sodium pyruvate (Robertson, 1942). All solutions were made up with glassdistilled water.…”

Organic Polyvalent Iodine Compounds

“…CeHalCla + 20H' -C6H5IO + 2C1" + H20 (b) Direct oxidation of the iodo compound has been effected using fuming nitric acid (130), potassium permanganate in dilute sulfuric acid (12), ozone (78), peracetic acid (9,45) followed by hydrolysis, potassium persulfate (108), and presumably other oxidants. The reagent is conveniently prepared by the combination of iodine, an iodate, and sulfuric acid (92).…”

Ru‐Catalyzed Oxidations with Iodosylbenzene Derivatives. Substituent Effects on Selectivity in Oxidation of Sulfides and Alcohols

“…The iodosyl compounds were prepared by oxidation of the corresponding iodo derivatives according to published procedures: PhIO by oxidation of iodobenzene with C12, followed by reaction with NaOH [23]. The same sequence was used with slight modifications to obtain rn-HOOCPhIO [20], p-MeOPhIO [24], p-OzNPhIO [25], o-HOOCPhIO [26] and rn-CsH4NIO [27]. PhIO2 was obtained by disproportionation of PhIO by heating [23].…”
