Efficient C–B Bond Formation Promoted by N-Heterocyclic Carbenes. Synthesis of Tertiary and Quaternary B-Substituted Carbons through Metal-Free Catalytic Boron Conjugate Additions to Cyclic and Acyclic α,β–Unsaturated Carbonyls
[Image: see text] Metal-free, nucleophilic activation of a B–B bond has been exploited in the development of a highly efficient method for conjugate additions of commercially available bis(pinacolato)diboron to cyclic or acyclic α,β-unsaturated carbonyls. Reactions are readily catalyzed by 2.5–10 mo...
