Carbon‐selenium and carbon‐tellurium cross‐couplings of arylboronic acids with diselenides and ditellurides have been catalyzed by iron(0), iron(II) chloride or iron(III) chloride without any ligand and additive in the air. The method yields the corresponding unsymmetrical diorgano monoselenides and monotellurides in good to excellent yields, displays a broad substrate scope, and is simple, convenient
芳族硼酸与二硒化物和二碲化物的碳-硒和碳-碲交叉偶联已经被空气中没有任何配体和添加剂的铁(0),氯化铁(II)或氯化铁(III)催化。该方法以良好至优异的产率产生相应的不对称二有机单硒化物和单碲化物,显示出广泛的底物范围,并且简单,方便,有效,经济和环境友好。
