Claims
- 1. A process for the preparation of aromatic dicarboxylic acids which comprises reacting an aromatic diiodide having about 5 to about 20 atoms in the ring or rings thereof, with carbon monoxide in the presence of a soluble homogeneous rhodium catablyst in a reaction medium selected from acetic acid, butyric acid and propionic acid.
- 2. The process of claim 1 wherein said aromatic diiodides is a toluene diiodide, benzene diiodide, naphthalene diiodide, pyridine diiodide, thiophene diiodide, or pyrrole diiodide.
- 3. The process of claim 2 wherein the reaction temperature is about 50.degree. to 150.degree. C.
- 4. A process for the preparation of aromatic organic acid compounds which comprises reacting an aromatic iodide of the formula
- I--R--I
- wherein R represents a substituted or unsubstituted group derived from toluene, benzene, naphthalene, pyridine. thiophene, or pyrrole,
- with carbon monoxide in the presence of a soluble homogeneous rhodium catalyst in a reaction medium selected from acetic acid, butyric acid and propionic acid.
- 5. The process of claim 4 wherein R represents a group derived from benzene or naphthylene.
- 6. The process of claim 5 wherein the reaction temperature is about 80.degree. to 130.degree. C.
- 7. The process of claim 6 wherein said reaction medium is acetic acid.
- 8. The process of claim 7 wherein said R is benzene.
