METHOD FOR OLEFIN OLIGOMERIZATION
The present invention relates to a method for olefin oligomerization and comprising i) injecting an olefin monomer and a solvent into a continuous stirred tank reactor (CSTR); ii) injecting an oligomerization catalyst system comprising a ligand compound, a transition metal compound, and a co-catalyst into the continuous stirred tank reactor; and iii) performing a multimerization reaction of the olefin monomer, wherein a ratio of the flowing rates of the olefin monomer and the solvent is from 1:1 to 2:1. In the method for olefin oligomerization according to the present invention, high linear alpha-olefin selectivity may be attained even with a small amount of a solvent used by controlling reaction conditions during the multimerization reaction of olefin by a continuous reaction using a continuous stirred tank reactor.

Methods of Preparing Primary Phosphine Products Using Lewis Acid Catalysts
Methods of preparing primary phosphine products using one or more precursor cyclophosphanes, hydrogen, and one or more Lewis acid catalysts. In some embodiments, a cyclophosphane precursor and at least one Lewis acid are dissolved in a solvent to provide a solution. The solution is treated with hydrogen, and optionally heated, to cause a reaction that produces a primary phosphine © product. The primary phosphine product may be isolated from the Lewis acid(s) and optionally purified. In some embodiments, a method may include synthesizing the cyclophosphane precursor prior to mixing the cyclophosphane precursor and the Lewis acid(s).
Compound of 3,3,3′,3′-tetramethyl-1,1′-spirobiindane-based phosphine ligand, and preparation method thereof

The compound of phosphine ligand is a compound having a structure represented by formula I or formula II, or an enantiomer, a raceme, or diastereomer thereof. The phosphine ligand can be prepared via a preparation scheme in which the cheap and easily available 6,6′-dihydroxyl-3,3,3′,3′-tetramethyl-1,1′-spirobiindane is used as a raw material and the compound represented by formula III serves as the key intermediate. The new phosphine ligand developed by the present application can be used in catalytic organic reaction, in particular as a chiral phosphine ligand that is widely used in many asymmetric catalytic reactions including asymmetric hydrogenation and asymmetric allyl alkylation, and thus it has economic practicability and industrial application prospect. ##STR00001##
PHOSPHINE REAGENTS FOR AZINE FLUOROALKYLATION
A new set of bench-stable fluoroalkylphosphines that directly convert C—H bonds in pyridine building blocks, drug-like fragments, and pharmaceuticals, into fluoroalkyl derivatives. No pre-installed functional groups or directing motifs are required. The reaction tolerates a variety of sterically and electronically distinct pyridines and is exclusively selective for the 4-position in most cases. The reaction proceeds via initial phosphonium salt formation followed by sp.sup.2-sp.sup.3 phosphorus ligand-coupling, an underdeveloped manifold for C—C bond formation.

In general formula (I), each of R.sup.1 to R.sup.5 represents a hydrogen atom, an alkoxy group of 1 to 10 carbon atoms, an alkyl group of 2 to 10 carbon atoms (or an alkyl group of 1 to 10 carbon atoms in the case of R.sup.3 to R.sup.5), an aryl group of 6 to 12 carbon atoms, an amino group, a monoalkylamino group of 1 to 10 carbon atoms, a dialkylamino group of 2 to 20 carbon atoms, a carboxy group, a cyano group, a fluoroalkyl group of 1 to 10 carbon atoms, or a halogen atom (provide that R.sup.1 and R.sup.2 are not both hydrogen atoms). ##STR00001##
TROPOMYOSIN-RELATED KINASE (trk) INHIBITORS
Tropomyosin-related kinase inhibitors (Trk inhibitors) are small molecule compounds useful in the treatment of disease. Trk inhibitors can be used as pharmaceutical agents and in pharmaceutical compositions. Trk inhibitors are useful in the treatment of inflammatory diseases, autoimmune disease, defects of bone metabolism and/or cancer, and are particularly useful in the treatment of osteoarthritis (OA), pain, and pain associated with OA. Trk inhibitors are also useful for inhibiting tropomyosin-related kinase A (TrkA), tropomyosin-related kinase B (TrkB), tropomyosin-related kinase C (TrkC), and/or c-FMS (the cellular receptor for colony stimulating factor-1 (CSF-1)).
