The preparation and the first structural characterization of arylamido complexes of Ir(I), having the general formula trans-Ir(CO)(NHAr)(PPh3)2, where Ar=Ph (1), p-C6H4Me (2), 2,6-C6H3Me2 (3), are described. Preliminary results of their facile insertion reactions with CO and CO2 are also discussed.

The synthesis and characterization of Ir(I)-arylamido complexes, trans-Ir(PPh3)2(CO)(NHAr), where Ar = C6H5, p-C6H4Me, o-C6H4Me, 3,5-C6H3Me2, 2,6-C6H3Me2, p-C6H4Cl, and p-C6H4NO2, are described. These complexes, except trans-Ir(PPh3)2(CO) [NH(p-C6H4NO2)], undergo rapid reactions with CO at atmospheric pressure and ambient temperatures. For the complexes containing the sterically bulky NH(3,5-C6H3Me2) and NH(2,6-C6H3Me2) ligands, the CO reactions generate carbamoyl moieties, which result from an insertion of CO into the iridium-nitrogen bond. The end products in the reactions of the other arylamido complexes with CO contain orthometalated carbamoyl moieties, with the generation of hydrido-Ir(III) centers. Intermediates leading to the formation of the orthometalated complexes are discussed.
