The oxidative addition of HBF4 and C4F9SO3H to the nitrogen complex trans-(Ph3P)2Ir(N2)Cl gives the hydrido iridium(III) complexes (Ph3P)2(N2)(Cl)Ir(H)X (X^-=FBF3^-, OSO2C4F9^-) in which the two excellent leaving groups(X^- and N2) can be successively substituted by weak and strong donors (H2O, CH3OH, CH3COCH3, THF, CH3CN, CO, C2H4, PPh3; dithiocarbamate, valinate). (Ph3P)2(L)(Cl)Ir(H)FBF3 (L=CO, N2) catalyze the isomerization of 1,2-diphenyl- and phenyloxirane to diphenyl and phenyl acetaldehyde, respectively.
