Metathesis of renewable unsaturated fatty acid esters catalysed by a phoban-indenylidene ruthenium catalyst
Autor: Robert P. Tooze, Roland Winde, Ronan Bellabarba, Ralf Karch, Grant S. Forman, Alexandra M. Z. Slawin
Publikováno v: Journal of Organometallic Chemistry. 691:5513-5516
The phoban-indenylidene complex is a robust catalyst for self-metathesis and ethenolysis reactions of methyl oleate. The phoban-indenylidene catalyst was characterized by X-ray analysis, NMR and microanalysis and was used in various self-metathesis a

Transition metal silyl complexes Part 54. Hydrido disilanyl complexes LnM(H)SiR2SiR2H (LnM = McCp(CO)2Mn, Cp(CO)2Re, (CO)3(PPh3)Fe)
Autor: Ulrich S. Schubert, Ralf Karch
Publikováno v: Inorganica Chimica Acta. 259:151-160
Hydrido disilanyl complexes of the type LnM(H)SiPh2SiPh2H are obtained from HPh2Si-SiPh2H by photochemical reaction with MeCp(CO)3 or by ligand exchange reactions starting from MeCpMn(CO)2(THF), Cp(CO)2Re(THF) or (CO)3(PPh3)Fe(H)SiMe3. The dinuclear
