The unusual alkyl nitrite starting material of the Barton reaction is prepared by attack of an alcohol on a nitrosylium cation generated in situ by dehydration of doubly protonated nitrous acid. [6] This series of steps is mechanistically identical to the first half of the mechanism formation of the more well-known aryl and alkyl diazonium salts.
Golden rain demonstration is made by combining two colorless solutions, potassium iodide solution and Lead(II) nitrate solution at room temperature to form yellow precipitate. During the chemical reaction, golden particles gently drop from the top of Erlenmeyer flask to the bottom, similar to watching the rain through a window.
In organic chemistry, a nitrate ester is an organic functional group with the formula R−ONO 2, where R stands for any organyl group. They are the esters of nitric acid and alcohols . A well-known example is nitroglycerin , which is not a nitro compound, despite its name.
Experiments with the Tree of Diana have inspired modern chemists to replicate its creation, using the process to analyze reactions between metals and other substances. A 1967 experiment at the University of Seattle studied the reaction between solid copper and aqueous silver nitrate. In it, silver ions reacted with the copper metal to form a ...
The report cites two women who had allegedly experienced Golden’s behavior. One of them said she was stalked by Golden “more than 10 times” and that he had sent her pictures of his genitalia.
