unprecedented copper‐catalyzed cross‐coupling reaction of the title compounds with diboron reagents is described (see scheme; Ts=4‐toluenesulfonyl). This reaction can be used to prepare both primary and secondaryalkylboronic esters having diverse structures and functional groups. The resulting products would be difficult to access by other means.

Rhodium-catalyzed cross-coupling reactions of unactivated primary alkyl chlorides with diboron reagents have been developed as practical methods for the synthesis of alkylboronic esters. These reactions expand the concept and utility of Rh(I)-catalyzed cross-coupling of aliphatic electrophiles. (C) 2014 Yao Fu. Published by Elsevier B.V. on behalf of Chinese Chemical Society.

New couple: The Cu‐promoted trifluoromethylation of primary and secondaryalkylboronicacids with TMSCF3 extends the scope of transition‐metal‐catalyzed trifluoromethylation reactions to sp3‐hybridized carbon centers. It also represents one of the first examples for Cu‐catalyzed CC cross‐coupling reactions of alkylboronicacid derivatives.

Palladium‐ and nickel‐catalyzed cross‐coupling recations of unactivated alkyl bromides with diboron reagents have been developed as practical methods for the synthesis of primary and secondaryalkylboronic esters. These reactions extend the concept and utility of Pd‐ and Ni‐catalyzed cross‐coupling of aliphatic electrophiles. They also show different substrate selectivity and ligand dependence as compared
