Alkenes and arenes possessing a bidentate directing group are alkylated with a primary or secondary alkylzinc halide in the presence of an iron/diphosphine catalyst and a dichloroalkane oxidant. Acrylamides, including unsubstituted and monosubstituted ones, react stereoselectively. Under these reaction conditions, β‐hydrogen elimination and homocoupling of the organometallic reagent are largely suppressed
在铁/二膦催化剂和二氯烷烃氧化剂的存在下,用伯或仲烷基卤化锌将具有二齿导向基团的烯烃和芳烃烷基化。丙烯酰胺,包括未取代的和单取代的丙烯酰胺,会发生立体选择性反应。在这些反应条件下,大大抑制了有机金属试剂的β-氢消除和均偶联。该反应可继续进行Ç通过 ħ活化催化由有机铁(III)的物种。
