摘要
The palladium-catalyzed cross-coupling reaction of trialkylbismuth reagents with aryl and heteroaryl halides and triflates is reported. Moderate to good yields were obtained for the transfer of primary alkyl groups. The reaction tolerates numerous functional groups on the electrophilic and nucleophilic partners. The cross-coupling of alpha-bromostyrene with tris(1,3-dioxan-2-ylethyl) bismuth is also reported.
