Non‐activated alkylelectrophiles, including alkyl iodides, bromides, tosylates, mesylates, and even chlorides, underwent copper‐catalyzedcross‐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

An efficient copper-catalyzedaddition of arylboronic esters to (Boc)2O was developed. The reaction can be conducted under exceedingly mild conditions and is compatible with a variety of synthetically relevant functional groups. It therefore represents a useful alternative route for the synthesis of methyl arylcarboxylates. A preliminary mechanistic study indicated the involvement of an addition–elimination

A copper-catalyzed Suzuki-Miyaura coupling of benzyl halides with arylboronates is described. Varieties of primary benzyl halides as well as more challenging secondary benzyl halides with beta hydrogens or steric hindrance could be successfully converted into the corresponding products. Thus it provides access to diarylmethanes, diarylethanes and triarylmethanes.
