A P(4-OMe-C6H4)3-catalyzed Michael addition/double bond migration tandem reaction between allenyl imide and indol-2-ones was developed. This synthetic strategy for diverse 1,3-dihydro-3-alkylidene-2H-indol-2-ones features operationally simple, good substrate scope, high chemoselectivity and mild reaction conditions. The proposed reaction mechanism is also provided.

Key words: indol-2-one, allene, phosphine catalysis, Michael addition, double bond migration
