H2 reacts with [Ir{(Ph2P)2N-p-C6H4CH3}2]Cl · 3 C6H6 (1) to give cis-[Ir(H)2{(Ph2P)2N-p-C6H4CH3}2]Cl · CH2Cl2 (2a). By reaction of 2a with NaBPh4 cis-[Ir(H)2{(Ph2P)2N-p-C6H4CH3}2]BPh4 (2 b) is obtained. Refluxing of 2a in CH2Cl2 yields trans-[lr(H)2{(Ph2P)2N-p-C6H4CH3}2]Cl · 1/2 CH2Cl2 (3a), which undegoes metatheses with NaBPh4 to trans-[Ir(H)2{(Ph2P)2N-p-C6H4CH3}2]BPh4 (3b). 3a is also formed by refluxing of 1 in methanol in the presence of oxygen. Oxidative addition of HCl to 1 and reaction with NaBPh4 yields trans-[Ir(H)(Cl){(Ph2P)2N-p-C6H4CH3}2]BPh4 (4b). The new compounds are characterised by their IR, Raman, 31P{1H} PFT and 1H NMR Spectra
