Application of 20859-23-8. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (S)-2-Bromosuccinic acid, is researched, Molecular C4H5BrO4, CAS is 20859-23-8, about Thiomalate complexes of gold(I): preparation, characterization and crystal structures of 1:2 gold to thiomalate complexes. Author is Leblanc, Daren J.; Smith, Richard W.; Wang, Zhixian; Howard-Lock, Helen E.; Lock, Colin J. L..
The preparation and characterization of 1:2 gold to thiomalate complexes, as ammonium salts, is described. The crystal structures of both racemic and optically pure samples, (NH4)5[AuL2]·H2O [H3L = thiomalic acid, HO2CCH(SH)CH2CO2H] are described and compared. In each case, the gold atom is linearly coordinated to two ligand sulfur atoms. Bond lengths and angles are normal.
There is still a lot of research devoted to this compound(SMILES：O=C(O)[C@@H](Br)CC(O)=O)Application of 20859-23-8, and with the development of science, more effects of this compound(20859-23-8) can be discovered.
