权利人:WISCONSIN ALUMNI RES FOUND
摘要:The present invention provides improved methods for synthesis of phosphinothiol reagents, as well as novel protected reagents, for use in formation of amide bonds, and particularly, for peptide ligation. The invention provides phosphine-borane complexes useful as reagents in the formation of amide bonds, particularly for the formation of an amide bond between any two of an amino acid, a peptide, or a protein.

摘要:New hexa-coordinate iron (II) complexes comprising compounds of formula (I) are described. These compounds comprise a tetradentate ligand with donor atoms comprising nitrogen and phosphorus. These complexes are shown for the first time to be useful catalysts for the hydrogenation of ketones, aldehydes, or imines to produce alcohols or amines, and the asymmetric hydrogenation of prochiral ketones or imines to produce non-racemic alcohols or amines. The source of the hydrogen can be hydrogen gas or a hydrogen-donating molecule such as isopropanol or hydrogen-donating mixture such as formic acid and an amine depending on the structure of the catalyst. In certain embodiments, the axial ligands on the catalyst comprise organonitrile ligands, carbonyl ligands, isonitrile ligands, or combinations thereof. The catalysts and the preparation thereof are disclosed. A reaction using phosphine and diamine precursors that is templated by the iron ion is the preferred route to the catalysts.

标题 :Synthesis of stable solutions of rare earth tris (organophosphate) in hydrocarbon solvents
发明人：YUNLU KENAN; HE MIN
权利人:RHODIA RARE EARTHS INC
摘要:Stable rare earth tris (organophosphate) solutions comprise a rare earth tris (organophosphate) and a hydrocarbon solvent. From about 2% to about 10% rare earth element, preferably from about 3% to about 8%, is present in the solutions. The rare earth tris (organophosphate) solutions are stable from precipitation of the rare earth tris (organophosphate) for at least about fifteen (15) days, preferably for at least about twenty (20) days and most preferably at least about thirty (30) days. A process for preparing these solutions is described herein. A stabilizing additive, acid, glycol or mixtures thereof, is utilized to inhibit precipitation. The molar ratios of free acid, glycol and/or water to the rare earth element are controlled to inhibit precipitation.
