The first nucleophilic allylic substitution reactions of triorganoindiumcompounds 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

Commercial sodium tetraphenylborate is a convenient phenylating reagent in the palladium(0)-catalyzed substitution of allylic acetates. Two phenyl groups of NaBPh4 are available for transfer. Triphenylboron is also a phenylating agent in this reaction.
