Inside Cover: Catalytic Asymmetric Functionalization of Aromatic CH Bonds by Electrophilic Trapping of Metal-Carbene-Induced Zwitterionic Intermediates (Angew. Chem. Int. Ed. 48/2014)
Graphical Abstract
An asymmetric three-component reaction of N,N-disubstituted anilines, diazo compounds, and imines is catalyzed by RhII and a chiral phosphoric acid and affords α,α-diaryl benzylic quaternary stereocenters. In their Communication on page 13098 ff., W. Hu, D. Xing et al. report this functionalization of aromatic CH bonds with diazo compounds, which they compare with a “magic tea pot” that allows the mixing of three different tea bags into a wonderful tea.
