multiple cascade reactions for the divergent assembly of fused N-heterocycles, comprising sequential activation of C–H and C–C bonds. Isolatable indene-type intermediates might be responsible for the generation of densely substituted fused pyridines, azepines, and azafluorenones products. The tolerance of stronglycoordinatingN-heterocycles, and those readily applicable for the late-stage modifications
