An unprecedented Ag-catalyzed addition reaction of cyclopropenones and nitrones to access imides was developed. Sequential C-C bond cleavage, N-O bond cleavage, and Mumm rearrangement were uncovered in this process. This protocol exhibited high efficiency, regioselectivity, good yields, and a broad tolerance of various functional groups.
