Organic synthesis epichlorohydrin

Applications of PTCs in organic synthesis include polymer reactions, aromatic substitutions, dehydrohalogenations, oxidations, and alkylations of sugars and carbohydrates. PTCs can be used jointly with organometallic complexes as cocatalysts, bonded to polymeric matrices and used in asymmetric syntheses (34). Industrial applications have been in the manufacture of pharmaceuticals, pesticides, and other chemicals, including epichlorohydrin and benzotrichloride. 

Ethylene Oxide and Epichlorohydrin Building Blocks in Organic Synthesis... 

The preferred catalysts are salts of inorganic and organic acids as well as tertiary amines. Phthalic anhydride, succinic anhydride and maleic anhydride are typical acid anhydrides, while ethylene oxide, propylene oxide, epichlorohydrin and phenyl glycidyl ether are typical epoxides. The synthesis of a ladder polymer was carried out by using bisanhydrides264. ... 

Reactions catalyzed by enzymes or enzyme systems exhibit far greater specificities than more conventional organic reactions. Among these specificities which enzymatic reactions possess, stereospecificity is one of the most excellent. To overcome the disadvantage of a conventional synthetic process, i.e., the troublesome resolution of a racemic mixture, microbial transformation with enzymes possessing stereospecificities has been appHed to the asymmetric synthesis of optically active substances [1-10]. C3- and C4-synthetic units (synthons, building blocks), such as epichlorohydrin (EP), 2,3-dichloro-l-propanol (2,3-DCP), glycidol (GLD), 3-chloro-l,2-propanediol (3-CPD), 4-chloro-... 

Chloropropene, allyl chloride, CH2=CH-CH2C1, is very reactive both as an organic halide and as an olefin and is, therefore, a starting material for further synthesis. Derivates of commercial importance are allyl alcohol, epichlorohydrin, and glycerol [370],...
