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.

Hydrido- and methyl-iridium(III) complexes (PPH3)2(CO)ClRIrX (1 - 4) (R = H, CH3) are formed by oxidative addition of acids HX with poorly coordinating anions X- (X- = O3SCF3-, O3SC4F9-, BF4-) and (CH3)3O+BF4-, respectively, to (PPh3)2(CO)ClIr.The excellent leaving groups X- can be substituted even by weak neutral ?- and ?-donors yielding cationic iridium(III) complexes +X- (5 - 9) (B = PPh3, CH3CN, H2O, (CH3)2CO, THF, C2H4).The structure of the key tetrafluoroborato complex (Ph3P)2(CO)Cl(H)IrFBF3 (3c) has been determined by X-ray structure analysis.
Hydridoiridium(III) Complexes with Terminal and Bridging Thio- and Selenocyanate

The thio- and selenocyanato complexes (Ph3P)2(CO)(Cl)(H)IrX 1 (X = SCN) and 2 (X = SeCN) have been prepared from the corresponding tetrafluoroborato- and trifluoromethanesulfonato-compounds (X = BF4, CF3SO3).The SCN ligand in 1 is S-bonded. 2 was obtained as a mixture of linkage isomers.The reaction of 2 with the tetrafluoroborato-complex (Ph3P)2(CO)(Cl)(H)IrFBF3 gives the salt +BF4- which contains the selenocyanate-bridged cation as a mixture of stereoisomers.
