biszulfitformákat
Biszulfitformákat, also known as bisulfite adducts or bisulfite derivatives, are chemical compounds formed when bisulfite ions (HSO₃⁻) react with certain functional groups in organic molecules. The most common reaction involves the addition of bisulfite to carbonyl groups, specifically aldehydes and ketones, forming α-hydroxyalkylsulfonates. This reaction is reversible and is often used in organic chemistry for purification and analysis.
The formation of bisulfite adducts is a nucleophilic addition reaction. The bisulfite ion acts as a nucleophile,
This property makes bisulfite adducts useful for separating aldehydes and ketones from mixtures containing other functional
Beyond carbonyl compounds, bisulfite can also react with other functional groups, although less commonly. For instance,
