Synthesis and characterisation of new PCsp3P-supported nickel complexes

Jonasson, Klara LU and Wendt, Ola LU (2014) In Journal of Organometallic Chemistry 759. p.15-18
Abstract
The coordination behaviour of the aliphatic pincer ligand cis-1,3-bis-((di-tert-butylphosphino)methyl) cyclohexane with NiCl2 and NiBr2 was studied. Reflux in toluene afforded cyclometalated, tridentate PCsp3P pincer complexes, that were characterised by elemental analysis and NMR spectroscopy; the solid state structures were determined by X-ray diffraction showing an unusually long Ni-Br bond in the bromo complex. A preliminary account of their reactivity is reported and they were found to be unreactive towards base and hydride sources and to be poor catalysts in Kumada coupling reactions. (C) 2014 Elsevier B.
