Keywords: crystal structure mol phosphonium bromide diphenyl dicarboxy preparation.They researched the compound: 8-Bromooctanoic acid( cas:17696-11-6 ).Reference of 8-Bromooctanoic acid. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:17696-11-6) here.
Quaternization of 3-(diphenylphosphino)propanoic acid with ω-haloalkanoic acids affords novel phosphonium salts containing two carboxy groups. The phosphonium salts were treated with 1 M alkali solution to obtain corresponding carboxylate phosphabetaines. The structure of the compounds was established by IR and NMR spectroscopy, elemental anal. and X-ray single crystal diffraction.
Different reactions of this compound(8-Bromooctanoic acid)Reference of 8-Bromooctanoic acid require different conditions, so the reaction conditions are very important.
