Sulfinic acid - Wikipedia
Sulfinic acids are oxoacids of sulfur with the structure RSO (OH). In these organosulfur compounds, sulfur is pyramidal. [1] Sulfinic acids RSO 2 H are about 1000-fold more acidic than the corresponding carboxylic acid RCO 2 H. [citation needed] Sulfur is pyramidal, consequently sulfinic acids are chiral.

2020年4月1日 · Sulfinate salts, also named sulfinic acid salts, were reported in the chemical literature as early as 1861. 1 They have been recognized as useful building blocks for organic synthesis and haven been studied extensively. 2 Generally, sulfinate salts are colorless, odorless, non-corrosive solids.
Sulfinic Acids in Organic Synthesis: A Review of Recent Studies
2021年6月30日 · Decade advances of sulfinic acids (2010-2021) were summarized via four categories by mechanisms: (1) sulfonyl radicals (2) RS radicals; (3) electrophilic intermediates; (4) nucleophilic S-reagents.
Recent advances in the application of sulfinic acids for the ...
2022年1月1日 · Recently, sulfinic acids as odorless, stable and readily available sulfur reagents have been increasingly employed for the synthesis of various important sulfur-containing compounds such as organic sulfones, sulfoxides, thioethers, sulfonamides and phosphorothioates with high synthetic efficiency and atom economy.
Sulfinic Acid - an overview | ScienceDirect Topics
Sulfinic acids are stable intermediates, but oxidize readily to sulfonic acid (RSO 3 H), the most highly oxidized species of thiols and disulfides (Eqn (10) and Figure 1). Strong oxidizing agents such as halogens, hydrogen peroxide, and nitric acid can generate sulfonic acids from thiols [26].
Sulfinic Acid - an overview | ScienceDirect Topics
Sulfonic acids have high melting points and probably exist as zwitterions. They are amphoteric, but mainly display the characteristics of weak acids. The sulfonic acid group activates an adjacent halogen to nucleophilic displacement, and may itself be displaced, e.g. reaction of alkylamines with benzimidazole-2-sulfonic acid.

Sulfinic acids are formed readily either by reduction of sulfonyl chlorides with zinc and alkaline solution or by alkaline hydrolysis of thiolsulfonates. Unlike the sulfonic acid, the sulfinic acid retains a lone electron pair on the sulfur atom and hence often...
