Hydrochloric Acid → Butyl undecanoate

Participants

Reaction Steps

A mixture of palladium chloride [27 mg, 0.15 mmol] and CuCl2 [41 mg, 0.30 mmol] in dioxane (10 ml) was stirred under carbon monoxide for 5 minutes. Then n-butyl formate (4 ml), 1-decene [0.75 g, 5.35 mmol] and aqueous hydrochloric acid (0.1 ml) were added and CO/O2 (1:1) was bubbled through the solution at room temperature and atmospheric pressure for a period of 24 hours. Analysis of the product gave n-butyl 2-methyldecanoate and n-butyl undecanoate with respectively 87% and 13% selectivity with a 64% conversion of the formic acid ester.
