Abstract
A mild, redox-neutral, alkylation of imines with potassium alkyl-trifluoroborates is described. The reaction proceeds under photo-redox conditions at ~30 °C with primary, secondary, and tertiary alkyltrifluoroborates, leading to alkylation products in moderate to good yield in most cases. Aryl-, vinyl-, and cyclopropyltrifluoroborates failed to react under the reported conditions.
