    • 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.

    • A process of the present invention produces an organic compound by allowing a compound containing an electron attractive group of following Formula (1):


      wherein Y is an electron attractive group; and R b and R c are each a hydrogen atom or an organic group, where Y, R b and R c may respectively be combined with each other to form a ring with an adjacent carbon atom, to react with a compound containing an unsaturated carbon-carbon bond of following Formula (2) or (7):

      wherein R d , R e , R f , R g , R i and R j are each a hydrogen atom or an organic group, where R d , R e , R f and R g may respectively be combined to form a ring with one or two adjacent carbon atoms, and R i and R j may be combined to form a ring with adjacent two carbon atoms,
      in the presence of oxygen and a catalytic compound of a Group 5, 6, 7, 8 or 9 element of the Periodic Table of Elements to yield a compound of following Formula (3) or (8):

      wherein Z is a hydrogen atom or a hydroxyl group; and Y, R b , R c , R d , R e , R f , R g , R i and R j have the same meanings as defined above. This process can efficiently produce a compound having an alkyl group or alkenyl group bonded at the alpha position of an electron attractive group, or a derivative thereof, by catalytic radical addition reaction.
