Alkyl bromides bathophenanthroline

Hiyama coupling reactions applying primary and secondary alkyl bromides or iodides 1 and aryltrifluorosilanes 21 (M = SiF3) catalyzed by 6.5 mol% NiBr2 DME and 7.5 mol% bathophenanthroline 12 are viable to obtain branched... 

Hiyama Cross-couplings. Organosilanes undergo crosscoupling reactions with both primary and secondary alkyl bromides or iodides. Trifluorosilanes are converted to the corresponding products using a nickel/bathophenanthroline catalytic system (eq 7). Moreover, the reaction is compatible with functionalities such as ketones, carbamates, aryl and alkyl chlorides, lactones, acetals, and nitriles. ... 

Recently, nickel-catalyzed cross-couplings of organosUicon reagents with unactivated secondary alkyl bromides have been disclosed. Functional groups such as fluoride, chloride, ether, lactones, ketones, acetals, and cyanides are stable under the reaction conditions. Bathophenanthroline appears to be the best ligand for these transformations [96]. 

Suzuki Cross-coupling Reactions. The formation of sp -sp carbon-carbon bonds is possible through the coupling of primary and secondary alkyl iodides and bromides with unsaturated boronic acids, under nickel catalysis using bathophenanthroline as ligand. As a result, an important variety of compounds bearing different functionalities can be coupled under mild conditions with good yields (eq 6). ...
