Formula: C3H4Br2O2. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 2,3-Dibromopropionic acid, is researched, Molecular C3H4Br2O2, CAS is 600-05-5, about Reaction of 2,3-Dihalopropionic Acids and Their Derivatives with P- and N-Nucleophiles.
3-(Triphenylphosphoniochlorido)acrylic and 2,3-dichloropropionic acids react with PPh3 to form 1,2-bis(triphenylphosphoniochlorido)ethane. Under analogous conditions, 2,3-dibromopropionic acid undergoes debromination followed by PPh3 addition to give, after H2O treatment, 3-(triphenylphosphoniobromido)propionic acid. 2,3-Dihalopropionitriles react similarly, providing 3-(triphenylphosphoniohalido) propionitriles. The reaction of 2,3-dibromopropionamide with PPh3 was performed to show that E-(triphenylphosphoniobromido)acrylic acid is capable, by contrast to what is reported previously, of reacting with PPh3. Pyridine forms with 2,3-dihalopropionic acids vinylpyridinium halides, while the reactions with aliphatic amines gives rise to dehydrohalogenation products.
Although many compounds look similar to this compound(600-05-5)Formula: C3H4Br2O2, numerous studies have shown that this compound(SMILES:O=C(O)C(Br)CBr), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
