Tetramethylethylenediamine (TMEDA) acts as cheap and readily removed ligand in the iron-catalyzed coupling of alkyl Grignard reagents and activated aryl chlorides. The use of TMEDA allows for low ligand and iron catalyst loading as well as an increased reaction concentration and an ambient reaction temperature on a mole scale.
四甲基乙二胺(TMEDA)在烷基格氏试剂和活化的芳基氯化物的铁催化偶合中起廉价且易于除去的配体的作用。TMEDA的使用允许低的配体和铁催化剂负载以及增加的反应浓度和摩尔规模的环境反应温度。
