Dual Co/Photoredox‐Catalyzed Regio‐ and Stereoselective Synthesis of Highly Functional 1,3‐Dienes
Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.A generic regio‐ and stereoselective protocol for the synthesis of functionalized 1,3‐dienes is presented that is facilitated via a dual Co/photoredox catalyst system while using modular 1,3‐enynes and unsaturated carbonyl derivatives as substrates. Key to the success of this transformation is the generation of a Co(III)H species that adds to the 1,3 ...
