Photocontrolled Cobalt Catalysis for Selective Hydroboration of α,β‐Unsaturated Ketones

Selectivity between 1,2 and 1,4 addition of a nucleophile to an α,β‐unsaturated carbonyl compound has classically been modified by the addition of stoichiometric additives to the substrate or reagent to increase their “hard” or “soft” character. Here, we demonstrate a conceptually distinct approach...
