Ag(I)-Catalyzed Hydroamination of 3-Butoxypropyne with Imidazole

Abstract It has been shown that imidazole adds to the triple bond of 3-butoxypropyne under the action of catalytic amounts (5 mol %) of silver salts to give a mixture of α and β isomers: 1-(3-butoxyprop-1-en-2-yl)-imidazole and 1-[(Z)-3-butoxyprop-1-en-1-yl)]-imidazole.
