Chloro propionic acid

The general plan of Organic Syntheses has been discussed in the prefaces of the previous volumes. In this volume are published two distinctly different methods of preparation for each of two compounds. The directions for producing /3-chloro-propionic acid first from acrolein and second from trimethylene chlorohydrin, and for producing trimethylacetic acid first from terJ-butyl chloride and second from pinacolone, have been included. This has been deemed advisable since in some countries one raw material is more readily available than the other. [Pg.143]

Phenoxypropionic acid herbicides contain a stereogenic center that can be derived from 2-chloro-propionic acid and include fluazifop-butyl (29) and flamprop (30).245... [Pg.606]

The halo aliphatic acid is chloro acetic or chloro propionic acid, the phenol being usually chlorinated before the final step. [Pg.752]

This partially undressed L-(-)-glucose behaves as the chiral equivalent of L-(-)-glucose diacetonide affording a-chloro propionic acid of (R)-configuration, with the same enantiomeric excess (Fig. 11) ... [Pg.186]

Finally, the lowest enantiomeric excess obtained with a-chloro propionic acid can be raised up to enantiomeric purity, by simply introducing a methylene group in place of the oxygen atom in the 5-position (ref. 16) (Fig. 12) ... [Pg.187]

There are many examples of reaction (a) e.g., arenediazonium chlorides add to acrylic and methacrylic acids esters, and nitriles giving / -aryl-unsaturated aldehydes afford 3-aryl-2-chloropropionaldehyde and the analogous 2-bromo aldehydes.245,246 Butadiene undergoes 1,4-addition.247-249 Phenylacetylene and a benzenediazonium chloride solution that has been neutralized with sodium carbonate solution gives, at 25-30°, a 46.5% yield of <%-chlorostilbene.250...

In a comparable system, (R,S)-ibuprofen can be separated by a membrane reactor [132] (see Fig. 5.18). The technique comprises a stereospecific hydrolysis by an enzyme. Subsequently, the enantiomeric ester is extracted into the organic phase on the other side of the membrane. In the system developed by Sepracor Inc., (R)-ibuprofen is selectively hydrolyzed by proteases in a hollow-fibre unit and the (S)-ibuprofen ester can be isolated at 100% yield. This configuration also applies for enantioseparation of other acids such as naproxen and 2-chloro-propionic acid. [Pg.253]

Solubilities of modified polymers were determined by placing about one mg of product in about three ml of liquid. These mixtures were allowed to stand at room temperature, with occasional agitation for one week. The following liquids were tested acetone, acetonitrile, bromobenzene, chlorobenzene, 2-chloro-propionic acid, diethyl sulfate, dimethyl sulfoxide, hexachloro-acetone, 5% LiCl/dimethyl sulfoxide, 5% LiCl/dimethylfuran, toluene and triethylphosphate.
