Cross-Metathesis of Vinylsilanes with Styrene Catalyzed by Ruthenium−Carbene Complexes
TL;DR: In this article, a cross-metathesis of styrene with various vinyl-silanes, H2CC(H)SiR3, catalyzed by [Cl2(PCy3)2RuCHPh] (1) to give (E)-silylstyrene, (E)Ph(H),CC(h)Si R3, and ethylene is reported.
Journal ArticleDOI
On the way to heptahexaenylidene complexes : trapping of an intermediate with the novel m=c=c=c=c=c=c=cr2 moiety
Gerhard Roth,Helmut Fischer +1 more
TL;DR: In this article, the first alkenyl-substituted pentatetraenylidene complex (CO)5WC CCCC(NMe2)C(H)CCC(NME2)2 (4) was constructed by adding dimethylamine to the CeCζ bond.
Journal ArticleDOI
Complexes with Diamino-Substituted Unsaturated C3 and C5 Ligands: First Group 6 Pentatetraenylidenes and New Allenylidene Complexes
Gerhard Roth,Helmut Fischer +1 more
TL;DR: The first diamino-allenylidene complexes with s-cis conformation were obtained by as mentioned in this paper, where they were stable at room temperature with the addition of HNMe2 within 30 min.
Journal ArticleDOI
Transfer of heterocyclic carbene ligands from chromium to gold, palladium and platinum
Florian Kessler,Normen Szesni,Chaya Maaß,Christiane Hohberger,Bernhard Weibert,Helmut Fischer +5 more
TL;DR: In this article, the solid-state structures of several of these heterocyclic carbene complexes including the structure of the binuclear Pd-Ag complex are established by X-ray structure analyses.
Journal ArticleDOI
Bimetallic Complexes with Conjugated C4, C6, C10, and C14 Bridges: Synthetic Routes to Alkynediyl-Bridged Bis(carbene) Complexes†
TL;DR: The reaction of [(CO)5WC(Ph)H] with Me2NC⋮CNMe2 affords two complexes: the binuclear complex and insertion product.
