How would you prepare diazonium salt?
Diazonium salt can be prepared by treating an aromatic amine (for example, phenylamine) with the mixture sodium nitrite and dilute hydrochloric acid at a temperature below 4°C. The following equation shows the conversion of phenylamine to benzenediazonium chloride.

Fluorobenzene can be prepared from benzene diazonium chloride by Balz-Shiemann reaction.
In this reaction aniline is to be treated with nitrous acid to form benzene diazonium chloride,which is further reacted with HBF₄ to form benzene diazonium fluorobarate.This is when heated,undergoes decomposition to give fluorobenzene.

Depends on what you mean by reversed but assuming you mean the reaction of the diazonium salt under some set of conditions to give product, generally no. In principle, all reactions are reversible but in practice, this may be difficult to achieve. In cases where the diazo group is lost (with the formation of nitrogen gas) (e.g., the Sandmeyer reaction) - no way to reverse it. However, azo compounds, formed from diazonium ions still have the nitrogens present and, in principle, could revert.

I had to pay to find this out, but “Chinen Salt”is actually the supplement Berberine HCL, a salt derived from the Berberis Aristata plant, also known as the Barberry Plant. the Supplement that you are looking for to help with diabetes and high blood pressure is known as BERBERINE HCL. Taking 500 mg twice a day WITH FOOD will help with type 2 diabetes and high blood pressure. Consult with your doctor. Chinen Salt is Berberine. Berberine is Chinen Salt. I am posting this as a public service to all.

When anisole reacts with strong acid like HCl, it undergo hydrolysis to form phenol and methyl chloride.
When p-methoxy aniline is reacted with NaNO2 and HCl, ether will dissociate to phenol so it's difficult to form anisole diazonium salt.

The following steps are involved in the preparation of fluorobenzene :
• C6H5N2+Cl- on treatment with HBF4 gives C6H5N2+BF4– and HCl.
•C6H5N2+BF4- on heating gives C6H5F( Fluorobenzene), BF3 and N2.
