Precise control of selective hydrogenation of α,β-unsaturated aldehydes in water mediated by ammonia borane

Hydrogenation of unsaturated biomass in a control manner is highly desirable but challenging, especially under mild conditions. We here report selective hydrogenation of α,β-unsaturated aldehydes (UALs), featuring a precise control of all potential products by adjustment of the role of ammonia boran...
