Publikováno v: Journal of Organometallic Chemistry. 821:136-141

Reaction of the gyroscope like complex (trans-1c) and p-tolSeSiMe3 (3.8 equiv, 85 °C, melt) gives the disubstitution product (trans-3c, 63%) and ClSiMe3. Attempts to access a monochloride complex via monosubstitution were unsuccessful. However, when

Rational Design of Highly Active 'Hybrid' Phosphine–Phosphinite Pincer Iridium Catalysts for Alkane Metathesis

Autor: Brad C. Bailey, Richard R. Schrock, Carolyn Supplee, Maurice Brookhart, Alan S. Goldman, Agnieszka J. Nawara-Hultzsch, Jason D. Hackenberg, Benudhar Punji, Thomas J. Emge

Publikováno v: ACS Catalysis. 3:2505-2514

Both the bisphosphine and bisphosphinite pincer complexes (tBu4PCP)IrH2 and (tBu4POCOP)IrH2 can cocatalyze alkane metathesis in tandem with olefin metathesis catalysts, but the two complexes have different resting states during catalysis, suggesting

Publikováno v: Polyhedron. 30:2530-2534

The complexation of the simple 1-hydroxymethyl-3,5-dimethylpyrazole (HL) ligand with Fe and Ni salts leads to interesting polynuclear complexes in good yield. X-ray diffraction reveals that the resulting complexes (μ4-L)4Ni4Cl4(H2O)4 and (μ2-L)4(μ

Publikováno v: Angewandte Chemie International Edition. 50:6647-6651

Molecules and macromolecules that undergo topologically complex dynamic processes—such as knot-forming and multistep folding sequences—have attracted considerable attention from numerous standpoints. However, there is much less awareness that cer
