alkylindium reagents with diaryliodonium salts proceeded efficiently in the presence of tetrakis(triphenylphosphine)palladium [Pd(PPh3)4], 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (SPhos), lithium tert-butoxide, and lithium chloride in DMA/THF (1:1) at 100 °C, leading to the corresponding cross-coupling products in moderate to good yield with broad substrate scope and wide functional group tolerance
在四(三苯基膦)钯[Pd(PPh 3 ) 4 ]、2-二环己基膦基-2',6'-二甲氧基联苯(SPhos)、叔丁基锂的存在下,钯催化的烷基铟试剂与二芳基碘鎓盐的交叉偶联有效地进行-丁醇和氯化锂在 DMA/THF (1:1) 中在 100 °C 下,导致相应的交叉偶联产物具有中等至良好的产率,具有广泛的底物范围和广泛的官能团耐受性。
