The Front Cover shows an artist with benzene‐shaped hair painting polyfunctional (hetero)arenes on a canvas in dark blue with a big brush. The color symbolizes the active cobalt catalyst, which is used for several transformations described within this Minireview. This marvelous combination of a zinc brush together with the cobalt dye enables the creation of pure art. In their Minireview, F. H. Lutter et al. describe that, due to their relatively low toxicity and price, cobalt‐salts offer a useful alternative to other common metal catalysts (e. g. palladium complexes). This Minireview highlights the suitability of cobalt catalysts for cross‐coupling and electrophilic amination reactions with organozinc pivalates, a class of organozinc reagents with enhanced stability towards air and moisture. More information can be found in the Minireview by F. H. Lutter et al. on page 5188 in Issue 21, 2019 (DOI: 10.1002/cctc.201900070).
