The synthesis of symmetrical 3,3′-bisoxindoles from simple acyclic β-oxoanilides is reported. The described method forges three new C–C bonds in a single step via a sequential Mn(OAc)3·2H2O mediated oxidative radical cyclization-fragmentation–dimerization process. The scope of this reaction is demonstrated in the preparation of a variety of 3,3′-bisoxindoles, as well as its application toward the formal
