The palladium-catalyzedcross-couplingreaction of tricyclopropylbismuth with aryl and heterocyclic halides and triflates is reported. The reaction tolerates numerous functional groups and does not require anhydrous conditions. The method was successfully extended to the cross-coupling of triethylbismuth.
An efficient nickel-catalyzed regioselective hydroarylation of 1,3-dienes with arylhalides and using silanes as hydride source is developed, affording functionalized arenes in good to excellent yields under mild conditions. The protocol shows a high tolerance to various functional groups on both the dienes and aryl coupling partners. Mechanism studies indicate that π-allyl nickel species is likely
