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

An efficient method for the cross-coupling reaction of primary trialkybismuth reagents with 2-haloazines and diazines is reported. The reaction functions with pyridines, pyrimidines, pyridazines and pyrazines and tolerates many functional groups. This method gives access to 2-alkylazines and diazines, a class of compounds which is important in medicinal chemistry.
