Pincer-ligated (PCP)Ir-based complexes have proven to be valuable catalysts for the dehydrogenation of alkanes and alkyl groups. As a versatile starting point from which we can access a wider range of new (PCP)Ir complexes, we have synthesized the iodo-substituted PCP ligand precursor (I-PCP-H), 1,3-bis[(di-tert-butylphosphino)methyl]-5-iodo-benzene, and the corresponding iridium complex {k³-2,6-bis[(di-tert-butylphosphino)methyl]-4-iodophenyl}iridiumhydridochloride ((I-PCP)IrHCl). In addition, the I-PCP-H precursor has been converted to the lithio salt Li-PCP-H. This should allow us to access PCP precursors with varying electronic properties, as well as PCP ligand derivatives that can be covalently linked to supporting materials such as silica. In addition, we have made bromo-substituted (PCP)Ir complexes, {k³-2,6-bis[(di-tert-butylphosphino)methyl]-4-bromophenyl}iridiumdibromide ((Br-PCP)IrBr₂), and (Br-PCP)IrPhBr via bromination of an unsubstituted-pincer iridium complex. The complexes have all been characterized by ¹H, ³¹P and ¹³C NMR spectroscopy, and by x-ray crystallography in the case of (Br-PCP)IrPhBr.
