P-chloro-o-cresol is the precursor for the pesticides MCPA (2-methyl-4-chloro-phenoxyacetic acid), MCPP (2-methyl-4-chloro-phenoxy propionic acid) and MCPB (2-methyl-4-chloro-phenoxy butyric acid). MCPP is also known as mecoprop. [Pg.117]

Verdini and coworkers [122] have introduced the 2-methyl-2-(2 -ni-tro)phenoxy-propionyl (Mnp) group for the preparation of stable monopro-tected gem-diamino alkyl residues 27 via IBTFA treatment of the carboxamide precursor 26. The precursor 26 is prepared by coupling amino a-carboxamide and 2-methyl-2-(2 -nitro)phenoxy-propionic acid as its O-succinimidyl ester 25. Hydrochloride salts, such as 27, are generally stable, crystalline compounds that can be stored at room temperature for several months. Once deprotonated, 27 is stable enough for acylation reactions (Scheme 9) [122]. [Pg.662]

A mixture of 8 g (0X)356 mol) of p-(2.2-dichlorocyclopropyl)phenol, 11.2 g (028 mol) of sodium hydroxide pellets, 11 g of chloroform and 350 ml of acetone was prepared at 0°C. The cooling bath was removed, the mixture stirred for a minute and then heated on a steam bath to reflux temperature. The reaction mixture was stirred at reflux for three hours and then concentrated in vacuo. The residual gum was partitioned between dilute hydrochloric acid and ether,and the ether layer was separated, dried and concentrated in vacuo. The residual oil (14 g) was partitioned between dilute aqueous sodium bicarbonate and ether. The sodium bicarbonate solution was acidified with concentrated hydrochloric acid and extracted with ether. The ether solution was dried over anhydrous sodium sulfate and concentrated. Theresidue(9.5gof yellow oil) was crystallized twice from hexane to give6.0gof 2-[p-(2,2-dichlorocyclopropyl)phenoxy] -2-methyl propionic acid in the form of a pale cream-colored solid, MP IM Cto 116°C.

CE has been used for the analysis of chiral pollutants, e.g., pesticides, polynuclear aromatic hydrocarbons, amines, carbonyl compounds, surfactants, dyes, and other toxic compounds. Moreover, CE has also been utilized to separate the structural isomers of various toxic pollutants such as phenols, polyaromatic hydrocarbons, and so on. Sarac, Chankvetadze, and Blaschke " resolved the enantiomers of 2-hydrazino-2-methyl-3-(3,4-dihydroxyphenyl)propanoic acid using CD as the BGE additive. The CDs used were native, neutral, and ionic in nature with phosphate buffer as BGE. Welseloh, Wolf, and Konig investigated the CE method for the separation of biphenyls, using a phosphate buffer as BGE with CD as the chiral additive. Miura et al., used CE for the chiral resolution of seven phenoxy acid herbicides using methylated CDs as the BGE additives. Furthermore, the same group resolved 2-(4-chlorophenoxy) propionic acid (MCPP), 2-(2,4-dichlorophenoxy) propionic acid (DCPP), (2,4-dichlorophenoxy) acetic acid (2,4-D), 2-(4-chlorophenoxy) propionic acid (2,4-CPPA), [(2,4,5-...
