What is pifa chemical?
Iodosobenzene bis(trifluoroacetate), bis(trifluoroacetoxy)iodobenzene, PIFA.
What is the use of Iodobenzene?
Iodobenzene is used in various C-C coupling reactions. It can be used in the preparation of iodobenzene dichloride, which is employed as an oxidant to oxidize alcohols to carbonyl compounds and as a chlorinating agent.
Is Iodobenzene an aromatic compound?
This compound belongs to the class of organic compounds known as iodobenzenes. These are aromatic compounds containing one or more iodine atoms attached to a benzene.
How is iodobenzene prepared?
Iodobenzene can be made from the reaction of benzene with iodine if they are heated under reflux in the presence of concentrated nitric acid, but it is normally made from benzenediazonium chloride solution.
How is iodobenzene formed?
Is iodobenzene volatile?
Iodobenzene is an organoiodine compound consisting of a benzene ring substituted with one iodine atom. It is useful as a synthetic intermediate in organic chemistry. It is a volatile colorless liquid, although aged samples appear yellowish.

What happens when Iodobenzene is heated with copper powder in a sealed tube?
Iodobenzene when heated with copper powder gives toluene/diphenyl .
How do you make Fluorobenzene?
First the chloride ion in benzene diazonium chloride is replaced with BF4− . The resulting compound eliminates nitrogen gas and boron trifluoride to give fluorobenzene. Note: This is a common method of preparation of fluorobenzene.
How do you prepare iodobenzene from benzene diazonium salt?
Making iodobenzene If you add cold potassium iodide solution to ice-cold benzenediazonium chloride solution, nitrogen gas is given off, and you get oily droplets of iodobenzene formed.
How is a diazonium salt converted into iodobenzene?
Substitution by an iodine atom If you add potassium iodide solution to the benzenediazonium chloride solution in the cold, nitrogen gas is given off, and you get oily droplets of iodobenzene formed. There is a simple reaction between the diazonium ions and the iodide ions from the potassium iodide solution.
