contribution describes catalytic tandem C−N and C−C bond-forming reactions involving the intramolecular hydroamination/bicyclization and intermolecular hydroamination/cyclization of olefins and alkynes using the organolanthanide complexes Cp‘2LnCH(SiMe3)2 and Me2SiCp‘‘2LnCH(SiMe3)2 (Cp‘ = η5-Me5C5; Cp‘‘ = η5-Me4C5; Ln = lanthanide) as precatalysts. In the case of the intramolecular processes, substrates of
