The first nucleophilic allylic substitution reactions of triorganoindium compounds with allylic halides and phosphates are reported. The reactions of trialkyl- and triarylindium reagents with cinnamyl and geranyl halides and phosphates, with the aid of copper catalysis [Cu(OTf)2/P(OEt)3], are described. In general, the reaction proceeds efficiently to give good yields and regioselectively to afford the SN2’ product.
