Mono-, di-, tri- and tetra-functional organotin compounds were easily prepared in a sonicated Barbier reaction using ultrasound technology via coupling reaction of organo halides with tin halides (Bu3SnCl, Bu2SnCl2, BuSnCl3, SnCl4) mediated by magnesium metal. The di- and tri- functional organotin compounds were tested in a Stille cross-coupling reaction in order to ascertain how many groups were transferred. (C) 2009 Elsevier B.V. All rights reserved.
