iodobenzene
Help anyone.........In the conversion of aniline to iodobenzene can I substitute sodium nitrate for the sodium nitrite I do not have. If not can I
readily convert sodium nitrate to the nitrite?

You'll want the nitrosonium ion (<sup>+</sup>N=O)in your diazotization, which won't be formed with NaNO3. For conversion of nitrate ->
nitrite look here:

I seems to me it's easier to make iodobenzene starting with benzene, otherwise you would have to find a way to convert and amine to the halogen you
seek..... solo

I have done the production of iodobenzene from aniline myself, and it worked nicely. You do need sodium nitrite though.
Go to the pharmacy and ask for it if necessary, or reduce your sodium nitate with molten lead.
The crude iodobenzene is black, and must be washed with HCl, NaOH and then redistilled.
