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.
