Anionic micellar systems were found to increase the rate of the acid catalyzed hydrolysis of acetylsalicylic acid (Nogami et al., 1962), methantheline bromide (Nogami and Awazu, 1962), n-butyl acetate, t-butyl acetate, ethyl p-aminobenzoate, and ethyl o-aminobenzoate (Sakurada et al., 1967), but decreased that of methyl benzoate slightly (Sakurada et al., 1967). The acid catalyzed hydrolysis of anionic amphi-philes also generally tend to be accelerated by micellization (Table 5). The rates of the acid catalyzed hydrolyses of sodium sulfoethyl do-decanoate, sodium undecanoate, and sodium sulfobutyl caprylate are significantly greater in micellar than in non-micellar solutions while that of sodium dodecyl sulfoacetate is unaffected by micelle formation (Meguro and Hikota, 1968).

Pentane-2,4-dione reacts with 3-chloro-l,2-benzisothiazole in the presence of sodium ethoxide to form 2-acetyl-3-aminobenzo[6]thiophen (71%). Under similar conditions, ethyl acetoacetate and diethyl malonate each give mainly ethyl 3-aminobenzo[6]thiophen-2-carboxylate (160). Under modified conditions diethyl malonate gives, in addition, some of the expected diethyl (l,2-benzisothiazol-3-yl)malonate, whereas ethyl cyano-acetate forms only ethyl (l,2-benzisothiazol-3-yl)cyanoacetate, irrespective of conditions. Mechanisms were considered involving iS-substituted o-cyanothiophenols as possible intermediates in the reactions leading to benzo[6]thiophen (see Scheme 8). The reactions constitute a useful...

The influence of NH., and CO, on the chromatographic behaviour of benzoic acid and its derivatives (o-, m-, p-hydroxybenzoic, nitrobenzoic, aminobenzoic, chlorobenzoic acids) was studied. The work was carried out by means of upgoing TLC on Sorbfil plates. Isopropanol- and ethyl acetate-containing water-organic eluents were used as mobile phases in the absence or presence of gaseous modifiers in the MP. The novel modification of TLC has been found to separate benzoic acids with different values of their dissociation constants more effectively than water-organic mobile phases.
