Abstract

Transition metal catalyzed cross-couplings are essential methods in organic synthesis. Due to their comparable low toxicity and price, cobalt-salts offer a useful alternative to other common metal-catalysts (e.g. palladium-complexes). In this review, we report that cobalt-catalysts are especially well suited for cross-coupling reactions with organozinc pivalates, a class of organozinc reagents with enhanced stability towards air and moisture. Furthermore, we discuss applications of cobalt-catalysis in Negishi cross-coupling reactions (sp(2)-sp(2), sp-sp(2), sp-sp(3)) as well as electrophilic aminations using organozinc reagents.
