Development of C–N coupling processes is fundamentally important and challenging for the synthesis of biologically active molecules and drugs. Herein, we report a highly atom efficient green process for the synthesis of α-ketoamides via visible-light induced copper(I) chloride catalysed direct oxidative Csp–N coupling reactions using commercially available alkynes and anilines at room temperature without

Multifunctional compounds, 2-hydroxybut-3-ynamides, are selectively synthesized using inexpensive and easy-to-handle solidcalciumcarbide as an alkynesource instead of inflammable and explosive gaseous acetylene through monoethynylation of 2-oxoacetamides.
