Mechanistic Insights into Formation of All-Carbon Quaternary Centers via Scandium-Catalyzed C–H Alkylation of Imidazoles with 1,1-Disubstituted Alkenes

This density functional theory (DFT) study reveals a detailed plausible mechanism for the Sc-catalyzed C–H cycloaddition of imidazoles to 1,1-disubstituted alkenes to form all-carbon quaternary ste...
