[1,5]‐Hydride Transfer/Cyclizations on Alkynyl Fischer Carbene Complexes: Synthesis of 1,2‐Dihydroquinolinyl Carbene Complexes and Cascade Reactions

Trigger happy: A new cascade process initiated by an unprecedented [1,5]-hydride transfer/cyclization of ortho-aminophenyl alkynyl Fischer carbene complexes leads to the formation of new 1,2-dihydroquinolinyl carbene complexes and 5,6-dihydrophenantridine derivatives (see scheme).
