Non‐activated alkyl electrophiles, including alkyl iodides, bromides, tosylates, mesylates, and even chlorides, underwent copper‐catalyzed cross‐coupling with aryl boron compounds and alkyl 9‐BBN reagents (see scheme; 9‐BBN=9‐borabicyclo[3.3.1]nonane). The reactions proceed with practically useful reactivities and thus complement palladium‐ and nickel‐catalyzed Suzuki–Miyaura coupling reactions of alkyl halides
非活化的烷基亲电试剂,包括烷基碘,溴化物,甲苯磺酸盐,甲磺酸盐,甚至氯化物,与芳基硼化合物和烷基9-BBN试剂进行铜催化交叉偶联(见方案; 9-BBN = 9-硼环[3.3 .1]壬烷)。该反应具有实用的反应性,因此可以补充钯和镍催化的烷基卤的Suzuki-Miyaura偶联反应。
