Received Date: 28 March 2005

Tin-indium were employed in the propargylations of various aldehydes with propargyl bromide in the presence of SnCl₂ and C₆H₅(CH₃)₃NBr under microwave irradiation to afford the corresponding homopropargyl alcohols exclusively in high yields. All the reactions were completed smoothly in predominantly aqueous media in 200 seconds only.
