The „platinum Grignard reagent” [Pt(MgCl)2(THF)x] (2), obtained by the reaction of PtCl2 and Et2Mg in a 1:2 molar ratio, as well as finely divided platinum (Pt*)—a possible intermediate formed during the preparation of 2—have been investigate

Structural investigation of bimetallic RH–Pt nanoparticles through X-ray absorption spectroscopy

Autor: Jacques Rozière, Joachim Richter, Deborah J. Jones, Helmut Bönnemann, Lorraine E. Aleandri

Publikováno v: J. Mater. Chem.. 5:749-752

The reduction, with tetraalkylammonium hydrotriorganoborates, of noble-metal salts suspended in tetrahydrofuran gives metal colloids which are protected against agglomeration by the surrounding tetraalkylammonium ions. The mean particle size of the i

X-ray absorption spectroscopy study of the Ti environment in MgH2 supported Ziegler catalysts

Autor: Lorraine E. Aleandri, Deborah J. Jones, Gerhard Fink, Volker Fraaije, Jacques Rozière

Publikováno v: Macromolecular Rapid Communications. 15:453-458

The EXAFS results indicate that the MgH 2 -supported Ziegler catalyst reveals a different type of active center fixation than that of the conventional MgCl 2 -supported catalysts. Furthermore the Ti species is not supported onto the MgH 2 surface sim

[HTiCl(THF) ∼0.5]x - a highly reactive titanium hydride and an active species in the McMurry reaction

Autor: Jacques Rozière, Deborah J. Jones, Lorraine E. Aleandri, Sigurd Becke, Borislav Bogdanović

Publikováno v: Journal of Organometallic Chemistry. 472:97-112

The complex [TiCl3(THF)3] reacts with catalytically-prepared solid magnesium hydride (MgH2★) or dissolved magnesium hydride (MgH2′) with evolution of hydrogen to give a highly reactive titanium hydride, [HTiCl(THF)∼0.5]x (1). The well-known low

[Ti(MgCl)2· xTHF]q: a reagent for the McMurry reaction and a novel inorganic Grignard complex

Autor: Andre Gaidies, Borislav Bogdanovicć, Jacques Rozière, Shijian Liao, Lorraine E. Aleandri, Deborah J. Jones, Alain Michalowicz, Andrea Schott

Publikováno v: Journal of Organometallic Chemistry. 459:87-93

The stepwise formation of two distinct bimetallic titanium/magnesium complexes during the reduction of TiCl3 (or TiCl4) by magnesium in tetrahydrofuran (THF) has been identified. [TiMgCl2·xTHF] (1) is produced in a first stage, but reacts further wi
