Journal ArticleDOI
Coordination Site Selective Janus Head Ligands
TL;DR: The deprotonation of PhP(CH2Py)2 (Py = 2-pyridyl) (1) leads to a Janus head ligand, in which one coordination site is provided by the two carbanionic CH bridges, while the two ring nitrogen atoms a...

Acetylenetitanium Complex Stabilized by Aminopyridinato Ligands
Awal Noor,Rhett Kempe +1 more
TL;DR: The first acetylenetitanium complex stabilized by aminopyridinato ligands has been prepared by the reaction of Ap2TiCl2 (1) with equimolar amount of bis(trimethylsilyl)acetylene in the presence of magnesium as mentioned in this paper.
Journal ArticleDOI
Triamidoamine complexes of chromium(III) and chromium(IV).
TL;DR: Both compounds are high-spin complexes bearing three and two unpaired electrons, respectively, revealing a trigonal monopyramidal and trigonal bipyramidal coordination geometry of the chromium center.
Journal ArticleDOI
Bis(amido)cyclodiphosph(III)azane Complexes of Yttrium and the Lanthanides
TL;DR: The first cyclodiphosph(III)azane complexes of the rare-earth elements have been synthesized and a heterocubane-type structure is observed in the solid state.
Journal ArticleDOI
Early and Late Transition Metal Complexes Stabilised by Imidazopyridazine-Substituted Bisamido Ligands
TL;DR: In this article, a series of new imidazo[1,5-b]pyridazine-substituted diamines (5) is reported, which can be synthesised by the nucleophilic ring transformation of 2-amino-5-methyl-1,3,4-oxadiazolium halogenides with diaminoalkanes followed by condensation reactions with 1,3-diketones.

Ordered mesoporous molecular sieves synthesized by a liquid-crystal template mechanism
TL;DR: In this paper, the synthesis of mesoporous inorganic solids from calcination of aluminosilicate gels in the presence of surfactants is described, in which the silicate material forms inorganic walls between ordered surfactant micelles.
Journal ArticleDOI
A new family of mesoporous molecular sieves prepared with liquid crystal templates
Jeffrey S. Beck,James C. Vartuli,Wieslaw J. Roth,M. E. Leonowicz,Charles T. Kresge,Kirk D. Schmitt,Cynthia Ting-Wah Chu,David H. Olson,E. W. Sheppard,S. B. McCullen,J. B. Higgins,J.L. Schlenker +11 more
TL;DR: In this paper, the synthesis, characterization, and proposed mechanism of formation of a new family of silicatelaluminosilicate mesoporous molecular sieves designated as M41S is described.
Journal ArticleDOI
Stereospecific Olefin Polymerization with Chiral Metallocene Catalysts
TL;DR: In contrast to heterogeneous Ziegler-Natta catalysts, homogeneous metallocene-based catalysts as discussed by the authors allow efficient control of regio-and stereoregularities, molecular weights and molecular weight distributions, and comonomer incorporation.
Journal ArticleDOI
Synthesis and applications of supramolecular-templated mesoporous materials
TL;DR: The unique structure of MCM-41 silicates has provided for extremely attractive properties such as uniform pore sizes greater than 20 A, surface areas exceeding 1000 m2 g−1, and long-range ordering of the pores.
Journal ArticleDOI
The Search for New-Generation Olefin Polymerization Catalysts: Life beyond Metallocenes.
TL;DR: Even late transition metal complexes function as active and selective catalysts for α-olefin polymerization, and an intense search has developed for new-generation catalysts, in both academic and industrial research laboratories.
