Dihydrido Arene Iridium Triisopropylphosphine Complexes

Synthesis of the above-mentioned arene complexes of formula [(ii -arene) IrH2(P Pr3)]BF4 was carried out by the treatment of acetone solutions of [(T] -CisHis)IrH2(P Pr3)]BF4 with an excess of the arene. However, in the case of aniline 

The complex [(Ti -QH5CH2CH2P Pr2-K-P)lrH2]BF4 also reacts with diphenylacet-ylene, that acts as a hydrogen acceptor, to yield the shlbene complex [(p -QH5CH2CH2P Pr2-K-P)lr(Z-PhCH=CHPh)]BF4. The latter compound can also be 

The [(T -C6ld5Cld2Cld2P Pr2-K-P)lr(Cld2=CldMe)]BF4 complex reacts with acetonitrile to yield thearyUiydridocomplex[lrld(C6ld4CH2CH2P Pr2-K -C,P)(NCMe)3]BF4 as a consequence of an intramolecular C—Ff metalation. This arylhydrido complex
