摘要：

(Chemical Equotion Present). Iridium pyridyl species are key intermediates in the title reactions. Thermal elimination of benzene from complexes 1 (R = Me, Ph) creates a vacant coordination site accessible to unsaturated hydrocarbons. Subsequent intramolecular nucleophilic attack by the pyridyl nitrogen atom to the alkene or vinylidene leads to iridacyclic pyridylidene structures (see scheme). © 2010 Wiley-VCH Verlag GmbH & Co.
