Abstract

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.
