Process for preparing organic sulfur acids or salts thereof |
| abstract |
A process for preparing organic sulfur acids or salts thereof, which comprises reacting an organic substrate with a sulfur oxide in the presence of a metal compound catalyst in the absence of N-hydroxy- and N-oxo-cyclic imide compounds to thereby obtain the corresponding organic sulfur acid or a salt thereof. The organic substrate includes (a) methylene-bearing homo- and hetero-cyclic compounds, (b) compounds bearing methyne carbon atoms, (c) unsaturated compounds bearing methyl or methylene groups at the position adjacent to the unsaturated bond, (d) nonaromatic heterocyclic compounds having carbon-hydrogen bonds at the position adjacent to the heteroatom, (e) linear alkanes, and so on, while the sulfur oxide may be sulfur dioxide or the like. This process permits efficient production of organic sulfur acids or salts thereof under mild conditions. |
