AbstractThe Ir(III) pyridylidene (3) (Tp Me2 = hydrotris(3,5-dimethylpyrazolyl)borate) reacts with oxygen (air), under mild conditions, to afford a bicyclic ether-semiaminal species. The new structure derives formally from two oxidative events. One is dehydrogenative in nature (loss of 2 H) and the other consists in the insertion of an oxygen atom into a non-activated benzylic C ―C bond. The reaction has been extended to a related iridacycle that contains a pyrazol co-ligand instead of the pyridylidene. Nowadays, there is increasing interest in the use of O 2 as a
