A method for the synthesis of ketones from aldehydes and boronic acids via a transition‐metal‐free C−H functionalization reaction is reported. The method employs nitrosobenzene as a reagent to drive the simultaneous activation of the boronic acid as a boronate and the activation of the C−Hbond of the aldehyde as an iminium species that triggers the key C−C bond‐forming step via an intramolecular migration
