Synthesis
Several methods of obtaining astatobenzene are described.[2][3][4]
Homogeneous exchange between iodobenzene and astatine iodide at room temperature:
- C6H5I + AtI → C6H5At + I2
Also, synthesis from phenylhydrazine and astatine iodide:
- C6H5NHNH2 + AtI + I2 → C6H5At + N2 + 3 HI
Also, thermal decomposition of diphenyliodonium iodide containing diphenyliodonium astatide:
- (C6H5)2IAt → C6H5At + C6H5I
Uses
The compound is of scientific interest primarily in research contexts involving astatine chemistry and radiopharmaceutical applications, where astatine radioactive isotopes are used.[5][6]
