Oxidative-addition reactions of halogens and halocarbons to [{Ir(μ-aza)(CO)2}2]>, COA of Formula: C7H5BrN2, the main research area is azaindolate iridium complex oxidative addition; halogen oxidative addition azaindolate iridium complex; halocarbon oxidative addition azaindolate iridium complex; pyrrolopyridinate iridium complex oxidative addition.
The compound [{Ir(μ-aza)(CO)2}2] (1, aza = 7-azaindolate) is oxidized by AgBF4 in a donor solvent to [{Ir(μ-aza)(CO)2(S)}2]2+ (S = Me2CO, MeCN) and to the neutral complex [{Ir(μ-aza)(CO)2(O2CMe)}2] (2) by silver acetate. The head-to-tail (HT) and the head-to-head (HH) isomers of 1 undergo trans-annular oxidative-addition reactions with a variety of substrates. Halogens (X2) add to 1 giving the diiridium(II) complexes [{Ir(μ-aza)X(CO)2}2] (X = Cl (3), Br, iodo). In addition, bromine selectively attacks position 3 of the five-membered ring in the aza bridges, affording [{Ir(μ-azaBr)Br(CO)2}2] as a single isomer. MeI and polyiodomethanes react with both isomers of 1 to give the iodomethyl complexes [{Ir(μ-aza)(CO)2}2(I)(R)] (R = Me, CH2I, CHI2, or (CH2)3I) as a mixture of isomers. The relative disposition, HH and HT, of the bridging ligands is maintained in these reactions. Complex 1 is a powerful photoreductor that reacts with CHCl3 and CCl4 giving [{Ir(μ-aza)(CO)2}2(Cl)(R)] (R = CHCl2 or CCl3), resp., whereas compound 3 results from reaction with 1,2-dichloroethane. Reactions of complex 1 with di-Et acetylenedicarboxylate and di-Me acetylenedicarboxylate (A) afford the tetranuclear complexes of the type [{Ir(μ-aza)(CO)2}4(A)2].
