The synthesis and characterization of optically active phosphinooxazoline chloride complexes (SM and RM)-[(eta6-p- MeC6H4iPr)MCl(PN)]A (M = Ru, Os; PN = phosphinooxazoline ligand; A = counteranion) and the derived aqua complexes (RM and SM)-[(eta6-p-MeC6H4iPr)M(PN) (H2O)](A)2 are reported. The OPOF2-containing compounds (RM and SM)-[(eta6-p-MeC 6H4iPr)M(OPOF2)(PNiPr)][PF6] (M = Ru, Os; PNiPr = (4S)-2-(2-diphenylphosphinophenyl)-4-isopropyl-1,3-oxazoline) have been also prepared and characterized. The molecular structures of (S M)-[(eta6-p-MeC6H4iPr)MCl(PNiPr)] [SbF6] (M = Ru, Os), (SRu)-[(eta6-p-MeC 6H4iPr)RuCl(PNInd)][SbF6] (PNInd = (3aS,8aR)-2-(2-diphenylphosphinophenyl)-3a,-8a-dihydroindane [1,2-d]oxazole), and (RRu)-[(eta6-p-MeC6H4iPr) Ru(PNiPr)(H2O)][SbF6] and that of the OPOF 2-containing compounds (RRu and SRu)- [(eta6-p-MeC6H4iPr)Ru(OPOF 2)(PNiPr)][PF6] have been determined by X-ray diffractometric methods. Dichloromethane solutions of the aqua complexes [(eta6-p-MeC6H4iPr)M(PN)(H 2O)][SbF6]2 are active catalysts for the Diels-Alder reaction between methacrolein and cyclopentadiene. The reaction occurs rapidly at room temperature with good exo:endo selectivity (from 85:15 to 96:4) and moderate enantioselectivity (up to 47%). The intermediate Lewis acid-dienophile compound (RRu and SRu)- [(eta6-p-MeC6H4iPr)Ru(PNInd)(methacrolein)] [SbF6]2 was isolated, and the molecular structure of the S epimer was determined by diffractometric means. The osmium complexes (S Os and ROs)- [(eta6-p-MeC6H 4iPr)Os(PN)(H2O)][A]2 (PN = PNiPr, A = SbF 6, BF4; PN = PNInd, A = SbF6) evolve to the phenyl-containing compounds (SOs and ROs)- [(eta6-p-MeC6H4iPr)OsPh(PN?)][SbF 6] (PN? = (4S)-2-(2-hydroxyphenylphosphinophenyl)-4-isopropyl- 1,3-oxazoline (PNOHiPr), PN? = (3aS,8aR)-2-(2- hydroxyphenylphosphinophenyl)-3a,8a-dihydroindane[1,2d]oxazole] (PNOHInd)) and (SOs and ROs)-[(eta6-p-MeC6H 4iPr)OsPh(PNFiPr)][BF4] (PNFiPr = (4S)-2-(2- fluorophenylphosphinophenyl)-4-isopropyl-1,3-oxazoline), respectively, in which the phosphinooxazoline ligand incorporates a hydroxy or fluoro functionality. On the basis of spectroscopic and crystallographic observations, a common pathway for these reactions is proposed.

Enantiomerically pure ligands containing a 4,5-dihydrooxazole moiety tethered to an auxiliary sulfur or phosphorus donor have been prepared.These ligands have been exploited for palladium-catalysed asymmetric allylic substitution, providing enantioselectivity in the catalytic reaction is discussed in terms of the steric and electronic influences provided by the ligand.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. HPLC of Formula: C24H24NOP

Chemistry is an experimental science, Computed Properties of C24H24NOP, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 148461-14-7, Name is (S)-2-(2-(Diphenylphosphino)phenyl)-4-isopropyl-4,5-dihydrooxazole

A highly efficient one-pot procedure for the synthesis of complexes of the type [Ir(COD)(Phox)]X, where Phox is a (chiral) phosphinooxazoline ligand, X = PF6 or B[(3,5-(CF3)2C6H 3)]4 (BARF), is developed. Former reported syntheses demanded the isolation of pure ligands by column chromatography, but the ligands tend to adsorb irreversibly on silica. Moreover, the chromatography has to be performed with careful exclusion of air. The present method avoids this difficulties. The yields of the syntheses are comparable with those starting from the pure ligands. The method is also suitable for the preparation of complexes of the type [Rh(COD)(Phox)]BARF and [Rh(Phox)2]BARF.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.

Diastereoselective formation of chiral iridium hydrides containing the chiral P,N-chelate ligand (4S)-2-(2-(diphenylphosphino)phenyl)-4-isopropyl-1,3-oxazoline

The iridium complex [Ir(mu-Cl)(PN)(PPh3)]2 (1) reacts with H2 affording only the kinetic isomer OC-6-55-C of the dihydride [IrClH2(PN)(PPh3)] (2) and with methanol yielding, also exclusively, the thermodynamic isomer OC-6-53-C (2b) of the same dihydride; complex 2b has been characterised by X-ray diffractometric methods.

Cu(I)-Ming-phos Catalyzed Enantioselective [3+2] Cycloadditions of Glycine ketimines to beta-Trifluoromethyl Enones

A catalytic asymmetric [3+2] cycloaddition of glycine ketimines with beta-CF3 beta,beta-disubstituted enones was realized in the presence of a chiral copper(I)/Ming-Phos complex. This method provides an access to construct highly functionalized pyrrolidines bearing three contiguous stereocenters, which including a trifluoromethylated all-carbon quaternary stereocenter. The features of this reaction include high chemo-, diastereo-, enantioselectivity (up to >20:1 cr, >20:1 dr, 98% ee), readily available starting materials, well functional-group tolerance and mild reaction conditions. Control experiments demonstrate that the fluoro-substituent is crucial for the reactivity. (Figure presented.).

Diastereoselective and Enantioselective Palladium-Catalyzed Allylic Substitution of Substituted Fluorinated Methylene Derivatives

The diastereoselective and enantioselective allylation of substituted monofluorinated methylene derivatives with diaryl-substituted allylic acetates was accomplished under Pd catalysis. This method gave fluorinated allyl products with two stereogenic centers in one pot. The dr values of these reactions were strongly governed by steric demand of the diaryl-substituted allylic acetates and the substituted fluorinated methylene derivatives. The application of the branched allyl products in the synthesis of fluorinated 3,4-dihydro-2H-pyrrole 1-oxide was also explored.

Structure, stereochemistry and dynamics of tetranuclear polyhydride clusters containing chiral heterobidentate phosphanes

A novel chiral phosphane (S)-2-(4-isopropyl-2-oxazoline-2-yl)phenyl-di-N- pyrrolylphosphane (S-PyrPOx) based on asymmetric oxazoline ring has been prepared and characterised. Reaction of this ligand and its phenyl-substituted analogue (S-PhPOx) with H4Ru4-(CO)12 and H 3RhOs3(CO)12 gave substituted derivatives H4Ru4(CO)10-(1,1-PhPOx) (2), H 4Ru4(CO)10(1,1-PyrPOx) (3), and H 3RhOs3-(CO)10(1,1-PyrPOx) (4), which were structurally characterised by X-ray crystallography in solid state and by a variety ofmultinuclear NMR spectroscopic measurements in solution. In all studied clusters the coordinated ligands form five-membered chelate rings through phosphorus and nitrogen atoms of oxazoline moiety to afford a novel chiral center associated with the substituted metal atom. The substitution reactions demonstrate extremely high stereoselectivity, which results in formation of only one diastereomer in all three cases to give S,S isomer in 2 and S,R isomer in 3 and 4.
