A Pt(II)-catalyzed cyclization of (hetero)aryl-allenes were developed, providing controllable synthesis of substituted 2,3-dihydropyrroles and polyheterocyclic skeletons. Another notable feature of this method was the dual-role of the Pt(II) catalyst: initiation of the migration of the (hetero)arylmethylene group and the subsequent Friedel-Crafts type annulation.
