The palladium-catalyzed cross-coupling reaction of tri-alkylbismuth 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 α-bromostyrene with tris(1,3-dioxan-2-ylethyl)bismuth is also reported
报道了钯催化的三烷基铋试剂与芳基和杂芳基卤化物和三氟甲磺酸酯的交叉偶联反应。伯烷基的转移获得了中等至良好的产率。该反应耐受亲电和亲核伙伴上的许多官能团。α-溴苯乙烯与三(1,3-二恶烷-2-基乙基)铋的交叉偶联也有报道。
