Beschreibungen/Notizen

• A new pincer ligand framework based on the commonly used “POCOP” (POCOP = κ3-C6H3-1,3-(OPR2)2, R = tBu, iPr) motif is reported, in which two POCOP units are tethered using an anthracene linker to support bimetallic complexes. Metalation using Ir precursors affords products dictated by steric factors. A comparison of the reactivity of RPOCOP-supported Ir­(I) carbonyl monomeric and dimeric species with alkyl halides is explored. For R = tBu, the complexes are unreactive, but for R = iPr, both types of complexes react with alkyl halides to form Ir­(III) products.
