carbene/nickel-catalyzed redox-neutral hydroacylation of 1,3-dienes with aldehydes in water was reported. A wide range of aliphatic and aromatic aldehydes were directly coupled with 1,3-dienes, providing synthetically useful β,γ-unsaturated ketones or the corresponding ketones after hydrogenation in moderate to high yields and high atom economy. This protocol first demonstrated the compatibility of NHC catalysis
报道了1,3-二烯与醛在水中的协同N-杂环卡宾/镍催化的氧化还原中性氢化酰化。多种脂肪族和芳香族醛与 1,3-二烯直接偶联,以中等至高产率和高原子经济性提供合成有用的β,γ-不饱和酮或氢化后的相应酮。该协议首先证明了 NHC 催化与镍催化的相容性。水被用作唯一的溶剂,这在协同金属/有机催化体系中很少被报道。
