Group 10 metal complexes supported by pincer ligands with an olefinic backbone
The coordination chemistry of 2,2?-bis(di-iso-propylphosphino)-trans- stilbene (tPCH-CHP) with group 10 metal centers in a variety of oxidation states is reported; different coordination modes were observed depending on the oxidation state of the metal. With metal centers in the 0 or +1 oxidation state ((tPCH-CHP)Ni, [(tPCH-CHP)Pd]2, (tPCH-CHP)NiCl, (tPCH-CHP)NiI), eta2 coordination of the olefin occurs, whereas, with metals in the +2 oxidation state, C-H activation of the backbone, followed by rapid H-X reductive elimination, was observed, leading to an eta1 coordination of the backbone in (tPC-CHP)MCl (M = Ni, Pd, Pt). Employing the methyl-substituted analogue, 2,2?-bis(di-iso-propylphosphino)-trans- diphenyl-1,2-dimethylethene (tPCMe-CMeP), forced an eta2 coordination of the olefin in [(tPCMe-CMeP)NiCl]2[NiCl4]. The synthesis of the hydride complex (tPC-CHP)NiH was attempted, but, instead, led to the formation of (tPCH-CHP)Ni, indicating that the vinyl form of the backbone can function as a hydrogen acceptor. All metal complexes were characterized by multinuclei NMR spectroscopy, X-ray crystallography, and elemental analysis.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: catalyst-palladium, you can also check out more blogs about32005-36-0
