We present a straightforward protocol for making (phosphanyl-carbene)PdII complexes. These complexes have bidentate ligands containing an acyclic diamino- or aminooxy-carbene and a phosphane. The synthesis gives good yields (typically 70-90 %) for a

Insights into the Heck Reaction with PCP Pincer Palladium(II) Complexes

Autor: Michael R. Eberhard

Publikováno v: Organic Letters. 6:2125-2128

[reaction: see text] The Heck reaction of phenyl halides with styrene using a series of related PCP pincer palladium(II) complexes was studied in order to evaluate the effect of ligand structure and electronics on the catalytic activity and to invest

Autor: Michael R. Eberhard, Shiro Matsukawa, Yohsuke Yamamoto, Craig M. Jensen

Publikováno v: Journal of Organometallic Chemistry. 687:185-189

Synthetic routes towards novel PCP′ pincer ligands were devised. Ligand 1-(Pr2iPOCH2)-3-(Bu2tPCH2)(C6H4) is prepared in a three step synthesis from 1,3-benzenedimethanol and 1-(Pr2iPO)-3-(Bu2tPCH2)(C6H4) is accessible in three steps from 3-hydroxyb

Publikováno v: Journal of Organometallic Chemistry. 681:189-195

A series of new palladium(II) complexes derived from the well-known pincer complex [PdCl{(C 6 H 3 )(OP i Pr 2 ) 2 -2,6}] were synthesised: [PdX{(C 6 H 3 )(OP i Pr 2 ) 2 -2,6}] (X=Br − , I − , OAc − , OTf − ). A novel PCP′ pincer ligand 1-(

CATALYTICALLY ENCHANCED SYSTEMS FOR HYDROGEN STORAGE

Autor: Zhaohui Wang, Craig M. Jensen, Keeley Murphy, Xue-Qin Gu, Walter P. Niemczura, Michael R. Eberhard, Kristin K. Kumashiro, Dalin Sun, Sesha Sai Raman

Values for the ∆H ‡ of dehydrogenation NaAlH4 to Na3AlH6/Al and Na3AlH6 to NaH/Al and the reverse hydrogenation reactions have been determined through kinetic studies of 2 mol % Ti and Zr doped hydride. We find that the experimentally determined
