N,N-Dimethylanilines were coupled with α-azidochalcones using visible-light driven Ru(bpy)3(PF6)2 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 sp3 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%).
