. 1H-15 N heteronuclear single-quantum correlation (HSQC) to prove the formation of both acetamide and formamide. Cross-peaks are observed for the two chemically distinct amide hydrogens of acetamide (blue line dN = 114.0 ppm). For formamide cross-peaks are observed from the two chemically distinct amide hydrogens as well as the hydrogen bound to the carbonyl (orange line dN = 115.5 ppm). The pulsed electrolysis condition is 1s pulse at E an = -0.2 V was followed 1s pulse at E ca = -1.8 V and the loop was repeated for 30 min.
