Table . Optimization study of the electrochemical acylation/C-H chlorination cascade approach a a Reagents and conditions: Substrates 1 (0.2 mmol) and 2 (0.21 mmol) dissolved in DMA (4 mL) in an undivided cell at rt. Conversions were determined by 1 H-NMR against 1,3,5-trimethoxybenzene as the internal standard and LCMS; selectivity ratio in parentheses. 0 % conversion means no chlorinated product; only amide is formed.
