Iron-catalyzed cross-coupling of nonactivated primary alkyl fluorides with aryl Grignard reagents has been achieved by using the low-coordinate dinuclear iron complex [(IPr2Me2)Fe(μ2-NDipp)2Fe(IPr2Me2)] as the catalyst. This iron-catalyzed C(sp3)–F bond arylation reaction is applicable to a variety of aryl Grignard reagents and primary alkyl fluorides. The product pattern suggests the involvement of a
铁-催化已经通过使用所获得的与芳基格氏试剂未活化伯烷基氟化物的交叉耦合的低坐标双核铁配合物[(IPR 2我2)的Fe(μ 2 -NDipp)2的Fe(IPR 2我2)]作为催化剂。这种铁催化的C(sp 3)–F键芳基化反应适用于各种芳基格氏试剂和伯烷基氟化物。产品模式表明,在其C–F键断裂步骤中涉及一种自由基类型的机制。
