Автор: Eun Seong Kim, Il Nam Jung, Sang Il Hyun, Soon Hyun Hong
Принадлежит: Samsung Fine Chemicals Co Ltd

Provided is an organic chlorohydrosilane, a useful starting material for preparing silicon polymers and a method for preparing the same. More particularly, the present invention enables the synthesis of various novel organic chlorohydrosilanes in high yield by an exchange reaction between an Si—H bond of a chlorosilane which can be obtained in an inexpensive and easy manner and an Si—Cl bond of an another organic chlorosilane using a quaternary organic phosphonium salt compound as a catalyst. Since the catalyst can be recovered after its use and reused, the present invention is very economical and thus effective for mass-producing silicon raw materials.

Chelating Carbene Ligand Precursors and Their Use in the Synthesis of Metathesis Catalysts

Номер: US20130172568A1
Автор: Christopher M. Haar, David E. Gindelberger, Jason K. Woertink, Richard L. Pederson, Yann Schrodi
Принадлежит: Materia Inc

Chelating ligand precursors for the preparation of olefin methathesis catalysts are disclosed. The resulting catalysts are air stable monomeric species capable of promoting various methathesis reactions efficiently, which can be recovered from the reaction mixture and reused. Internal olefin compounds, specifically beta-substituted styrenes, are used as ligand precursors. Compared to terminal olefin compounds such as unsubstituted styrenes, the beta-substituted styrenes are easier and less costly to prepare, and more stable since they are less prone to spontaneous polymerization. Methods of preparing chelating-carbene methathesis catalysts without the use of CuCl are disclosed. This eliminates the need for CuCl by replacing it with organic acids, mineral acids, mild oxidants or even water, resulting in high yields of Hoveyda-type methathesis catalysts. The invention provides an efficient method for preparing chelating-carbene metathesis catalysts by reacting a suitable ruthenium complex in high concentrations of the ligand precursors followed by crystallization from an organic solvent.

The present invention provides methods for the synthesis of catalysts and precursors thereof. Methods of the invention may comprise combining a catalyst precursor and at least one ligand to generate a catalytically active species, often under mild conditions and in high yields. In some cases, a wide variety of catalysts may be synthesized from a single catalyst precursor. Methods of the invention may also include the preparation of catalysts which, under reaction conditions known in the art, may have been difficult or impossible to prepare and/or isolate due to, for example, steric crowding at the metal center. The present invention also provides catalyst compositions, and precursors thereof, which may be useful in various chemical reactions including olefin metathesis. In some cases, methods of the invention may reduce the number of synthetic and purification steps required to produce catalysts and/or other reaction products, as well as reducing time, cost, and waste production. 170-.

The present invention relates to novel stabilized cyclopropenylylidene cations and their use as ligands in metal catalysts.Phosphenium cations of the general formula [RP:]are isolobal with singlet carbenes and can be stabilized, for example, by donation of electron density in their empty orbital. This stabilization can, for example, be achieved by incorporation of the phosphorus atom in a heterocyclic backbone A or by reaction with bases with the formation of the corresponding Lewis adduct B (scheme 1).In both cases, the presence of a free electron pair on the phosphorus atom suggests the use of these compounds as ligands, though their intrinsic positive charge results in them being weak a donors and strong Π acceptors. In particular, in the adducts of type B, the resonance structure of Bdominates in the basic structure, if D is a phosphine, so that transition metal complexes, which can be derived from these compounds, are rare. Even in cases in which D is an N-heterocyclic carbene (NHC), the coordination properties of the ...
