Abstract
| - Palladium(0) and platinum(0) complexes Pd2(dba)3 and Pt(dba)2, reacted with p-benzoquinone (bq) and norbornene (nbe) to afford new dinuclear complexes possessing p-benzoquinone as a bridging ligand and norbornene as a monodentate ligand, Pd2(bq)2(nbe)2 and Pt2(bq)2(nbe)2, respectively.
- Palladium(0) and platinum(0) precursor complexes, Pd2(dba)3 and Pt(dba)2, reacted withp-benzoquinone (bq) and norbornene (nbe) to afford new dinuclear complexes possessingp-benzoquinone as a bridging ligand and norbornene as a monodentate ligand, Pd2(bq)2(nbe)2 and Pt2(bq)2(nbe)2, respectively. The solid-state structure of the obtained complexespresented the short metal−metal distances similar to predecessors possessing the significantd10−d10 bonding interaction. The formations of the previously reported mononuclearp-benzoquinone and p-naphthoquinone complexes using 1,5-cyclooctadiene in place ofnorbornene were also unambiguously confirmed by the single-crystal X-ray diffraction studies.The present dinuclear palladium complex proved to be an efficient catalyst precursor forthe linear cotrimerization of 1-octene and dimethyl acetylenedicarboxylate. On the otherhand, the platinum analogue catalyzed the hydrosilylation of styrene under mild reactionconditions.
