Redox-Neutral 1,2-Dicarbofunctionalization of Buta-1,3-diene by Merging Decatungstate and Chromium Catalysis

Abstract Homoallylic alcohol is a significantly useful intermediate in organic synthesis. Here we establish a three-component Nozaki–Hiyama–Kishi (NHK) type reaction of buta-1,3-diene, aldehydes, and aliphatic C–H partners by merging decatungstate and chromium catalysis, enabling a modular, redox-neutral, and atom-economic strategy to access a diverse range of homoallylic alcohols.
