N,N-Dimethylanilines were coupled with α-azidochalcones using visible-light driven Ru(bpy)(PF) catalyzed photocascade continuous flow microfluidic approach that involves the creation of one C-C and two C-N new bonds. The reaction involves dual photocatalysis ensuing two sp C-H bond functionalization of N,N-dimethylanilines. To explore the scope of the reaction, 20 different 1,3-diazabicyclo[3.1.0]hexanes were synthesized in good yields (55-71%).
