Terminal alkynols react with formaldehyde and secondary amines in aqueous ionic liquid [emim]HSO4-, in the presence of Cu(OAc)(2) to afford the corresponding 1-(alpha-hydroxyalkyl)- or 1-(beta-hydroxyalkyl)-2-(aminomethyl)acetylenes in better yields in comparison with the reaction in conventional organic solvents. The catalytic system can be easily recovered and recycled.
