The Pinner Reaction is the partial solvolysis of a nitrile to yield an iminoether. Treatment of the nitrile with gaseous HCl in a mixture of anhydrous chloroform and an alcohol produces the imino ether hydrochloride. These salts are known as Pinner Salts, and may react further with various nucleophiles.
