Isoamyl ether iodide

Mercury di-isoamyl is insoluble in water, slightly in alcohol, but readily soluble in ether. It does not oxidise in air, but when dropj ed into chlorine it forms isoamyl mercuric chloride. In contact with solid iodine it reacts with a hissing sound, and the reaction with bromine is still more violent. An ethereal solution of mercury di-isoamyl treated first with alcoholic and then with solid iodine gives isoamyl mercuric iodide and isoamyl iodide. Treatment with an excess of mercuric chloride in alcohol yields isoamyl mercuric chloride.

Chloromercuri"2-isoamylthiophene is obtained in 75 per cent, yield after the reaction mixture has stood for four days. It crystallises from benzene in fine needles, M.pt. 171 5° to 172° C., readily soluble in cold acetone or warm ether, sparingly in other cold solvents. If treated with sodium iodide it yields mercury 5 5 -di-isoamyl-2 2 -dithienyl. 

Erlenmeyer found that the butyl alcohol present in fusel oil yields iso-butyric acid (see below) on oxidation, and is therefore isobutyl alcohol, and he also showed that from isobutyl iodide the same valeric acid is obtained as from the amyl alcohol of fusel oil, which is therefore isoamyl alcohol, derived from dimethylethylmethane. Secondary butyl alcohol was first obtained as hydrate de butylene from erythritol by de Luynes. A. Lieben obtained it from zinc ethyl and dichloroethyl ether, and since he found that on oxidation it gives a ketone he recognised it as secondary butyl alcohol. Lieben and A. Rossi obtained normal butyl alcohol from butyric acid, which was converted into butyraldehyde by distilling calcium butyrate and calcium formate, and a solution of this reduced with a large amount of sodium amalgam. They give structural formulae for the four butyl alcohols, with the boiling-points.
