A new method has been developed for the catalytic hydrochlorination of olefins and acetylenes in the presence of Rh complexes by means of HCl generated in situ from CH2Cl2 and CHCl3 under the reaction conditions.The reaction was studied using the hydrochlorination of propylene, 1-hexene, 1-nonene, vinylcyclopropane, 1,1-dicyclopropylethylene, cyclohexene, cyclooctene, norbornene, and 1,5-cyclooctadiene as examples.
Silver Nitrate-Alumina: A Chromatographic Reaction Medium for Conversion of 5-Halogenopent-2-enes into 1-Cyclopropylethyl Nitrate

A chromatography column of 30percent silver nitrate-neutral alumina provides a reactive surface for the ready conversion of 5-halogenopent-2-enes (1) into 1-cyclopropylethyl nitrate (2) upon elution with pentane.By this technique 5-bromopent-2-ene (1a) and 5-iodopent-2-ene (1b) are converted into (2) in 74 and 94percent yield, respectively, in less than five minutes. 5-chloropent-2-ene (1c) was unreactive under the same conditions.Reduced yields of (2) were observed when (1a) or (1b) were stirred, neat, with powdered silver nitrate.When acidic alumina was used to prepare the chromatography column and only partially dried, an efficient medium for hydrolysis to the corresponding alcohol resulted.Elution of (1a) with diethyl ether therefore gave 1-cyclopropylethanol (5) in 31percent yield and elution of (2) with diethyl ether gave (5) in ca. 100percent yield.
