Please i want to make iodobenzene, i have seen something aboute sandmeyer reaction, but i don´t know details about synthesis. Thank you

benzene, nitric acid, hydroiodic acid, or maybe iodine. I think. Shit you may be able to buy that.

iododbenzene could be made via a sandmeyer reaction this would invole taking analine and making a diazonium salt and then using Cu(1)I to make iodobenzene. if you want the spesific conditions there will be plently of information out there for u to find.

Generally, the Sandmeyer reactions that form iodobenzenes utilize potassium iodide instead of cuprous iodide.

CuI is a catalyst.

Treat benzene with HNO3 and KI.

Do you have a cite for that? Haloarenes generally don't undergo nucleophilic substitution unless there are strongly electron-withdrawing groups on the ring.

I was editing as you replied. See above.
