Astatobenzene is an organoastatine chemical compound with the formula . This is a compound in which an astatine atom, the rarest halogen, is bonded to a benzene ring.
Several methods of obtaining astatobenzene are described.
Homogeneous exchange between iodobenzene and astatine iodide at room temperature:
Also, synthesis from phenylhydrazine and astatine iodide:
Also, thermal decomposition of diphenyliodonium iodide containing diphenyliodonium astatide:
The compound is of scientific interest primarily in research contexts involving astatine chemistry and radiopharmaceutical applications, where astatine radioactive isotopes are used.
