Conversion of a C(sp(2))-H or C(sp(3))-H bond to the corresponding C-Me bond can be achieved by using AlMe3 or its air-stable diamine complex in the presence of catalytic amounts of an inorganic iron(III) salt and a diphosphine along with 2,3-dichlorobutane as a stoichiometric oxidant. The reaction is applicable to a variety of amide substrates bearing a picolinoyl or 8-aminoquinolyl directing group
C(sp(2))-H 或 C(sp(3))-H 键转化为相应的 C-Me 键可以通过使用 AlMe3 或其空气稳定的二胺配合物在催化量的无机铁 (III) 盐和二膦以及作为化学计量氧化剂的 2,3-二氯丁烷。该反应适用于各种带有吡啶甲酰基或 8-氨基喹啉基导向基团的酰胺底物,能够使各种(杂)芳基、烯基和烷基酰胺甲基化。使用温和的铝试剂可防止铁发生不希望的还原,并允许反应以高达 6500 的催化剂周转数进行。
