Dimethylacetic acid

Isobutyric acid, dimethylacetic acid, 2-methylpropanoic acid, (CHjjjCH COOH, colourless syrupy liquid with an unpleasant odour b.p. 154°C. Prepared by oxidation of 2-methylpropanol with K2Cr207 and H2SO4. Salts soluble in water. Used in alkaline solution for sweetening gasoline. [Pg.71]

Chemical Designation - Synonyms Dimethylacetic acid Isopropylformic acid 2-Methylpropanoic acid alpha-Methylpropionic acid Propane-2-carboxylic acid Chemical Formula (CH3)2CHCOOH. Observable Characteristics(asshipped) Liquid Color Colorless Odor Unpleasant, acrid. [Pg.215]

The clinical success of clofibrate has naturally led to the synthesis of numerous analogues intended for use as hypocholesterolemic agents. One of these, clofenpyride (84), is synthesized readily from p-< hlorophenoxy-2,2-dimethylacetic acid (83) by conversion to the acid chloride and reaction with 3-hydroxy-40... [Pg.101]

As another example, Lai et al. [189] reported the synthesis of carboxyl-terminated trithiocarbonates. The synthesis of S.S -bislaa -dimethylacetic acid)trithiocarbonate is presented in Scheme 31 and requires the use of carbon disulfide, which reacts with hydroxide ions. This synthesis yields trithiocarbonate with purities above 99%. [Pg.74]

No, the names given are the common names. The lUPAC names are ethanoic acid for acetic acid, propanoic acid for methylacetic acid, 2-methylpropanoic acid for dimethylacetic acid, and 2,2-dimethylpropanoic acid for trime ylacetic acid. [Pg.240]

Kawai et al. [27] have reported the synthesis of alkyne 7 after the stepwise formation of phenyl-2,2-dimethylacetic acid by double methylation of para-bromo-phenylacetic acid (Scheme 10.4). [Pg.131]

In this step, the sodium salt of 2-(4-bromophenyl)-2,2-dimethylacetic acid 13 was lithiated via a metal-halogen exchange using f-BuLi, and subsequently 4-[4-(hydroxydiphenylmethyl)piperidini-l-yl]butyraldehyde 14 was arylated to afford fexofenadine. [Pg.132]
