Two efficient enantioselective syntheses of 2-amino-1-phenylethanol

Two enantioselective methods for the synthesis of 2-amino-1-phenylethanol have been developed. The first utilizes an enantioselective oxazaborolidine- catalyzed borane reduction of 2-chloroacetophenone (phenacyl chloride) to give the chiral chloro alcohol in good yield with an ee in the 93-97% range. Reaction with dilute ammonium hydroxide produced the amino alcohol in good yield with a high ee. The second approach involved first the conversion of phenacyl chloride to the succinimido acetophenone which was then hydrogenated using a chiral ruthenium complex in conjunction with a base and an optically active amine (Noyori procedure). This gave the optically active succinimido alcohol in very good yield with an ee of 98%. Hydrolysis with dilute base produced the optically active amino alcohol in very good yield and excellent enantioselectivity.

Redox state switching of transition metals by deprotonation of the tridentate ligand 2,6-bis(imidazol-2-yl)pyridine

The chemistry of the ligand 1, 2,6-bis(imidazol-2-yl)pyridine with manganese, cobalt, nickel and ruthenium has been investigated. The ligand binds as a meridional tridentate ligand as shown by the crystal structures of [Mn(1)2](CF3SO3)2*Et2O and [Ru(1)2](PF6)2*2CH3CN*H2O. The coordinatedligand is deprotonated in mildly basic solution, and this leads to a dr op in the metal M(III)/M(II) reduction potential for cobalt and ruthenium of roughly 1.3 V. The crystal structure of Na2(PPN)[Co(1- 2H)2]2(OH)*MeOH*2H2O confirms the deprotonation and shows sodium to bind to the deprotonated nitrogen atoms. No stabilisation of the M(III) oxidation state was observed for nickel and manganese.

Novel platinum group metal complexes bearing bidentate chelating pyrimidyl-NHC and pyrimidyl imidazolyl-thione ligands: Syntheses, spectral and structural characterization

A family of novel platinum group metal complexes containing bidentate chelating 1-pyrimidyl-3-methylimidazolyl bromide (HL1¡¤Br) and 1-pyrimidyl-3-methylimidazolyl-2-thione (L2) ligands has been synthesized. The synthetic protocol for the formation of these complexes differs from one ligand to the other. Treatment of ligand (HL1¡¤Br) with the metal precursors led to the formation of complexes via in situ carbene transfer reactions. The silver-NHC complex (1) was formed by the reaction of HL1¡¤Br with silver oxide under light-free conditions. Subsequent addition of appropriate metal precursors to the silver-NHC complex yielded [(eta6-arene)Ru(L1)Cl] PF6 complexes {arene = C6H6 (2), p- iPrC6H4Me (3), C6Me6 (4)} on stirring at room temperature, whereas the complexes [CpRu(L1)(PPh 3)]PF6 {Cp = C5H5 (5), C 9H7 (6)} were obtained under reflux conditions. In the case of ligand L2, stirring of equimolar quantities of metal precursors and the ligand at room temperature yielded [(eta6-arene)Ru(L2)Cl]PF 6 {arene = C6H6 (7), p-iPrC 6H4Me (8), C6Me6 (9)}, and [Cp*M(L2)Cl]PF6 {Cp* = C5Me5, M = Rh (10), Ir (11)}. All these complexes were characterized by CHN analysis, IR, NMR and mass spectrometry besides confirmation by single crystal X-ray diffraction studies for some representative complexes as their hexafluorophosphate salts [3]PF6, [5]PF6, [8]PF 6 and [10]PF6.

Heteroditopic rhenium(I) and ruthenium(II) bipyridyl calix[4]arene receptors for binding cation-anion ion pairs

New heteroditopic ion pair receptors that contain rhenium(I) and ruthenium(II) bipyridyl amide anion recognition sites covalently linked to a lower rim calix[4]arene tetraester alkali metal cation binding site have been prepared and shown to bind alkali metal (Li+, Na+)-halide (Br-, I-) ion pair species. Proton NMR titration studies reveal the lower rim ester co-bound alkali metal cation significantly enhances the strength of bromide and iodide binding in acetonitrile solutions with the largest positive co-operative binding effect of sixtyfold observed with bromide and the lithium complex of one receptor. Solid/liquid extraction experiments show two of the receptors are capable of solubilising NaCl and NaOAc in dichloromethane solutions. The Royal Society of Chemistry 2001.

Self-assembly of highly luminescent heteronuclear coordination cages

Exo-functionalized Pd2L4 cage compounds with attached Ru(ii) pyridine complexes were prepared via coordination-driven self-assembly. Unlike most of the previously reported palladium(ii) cages, one of these metallocages exhibits an exceptionally high quantum yield of 66%. The presented approach is promising to obtain luminescent coordination complexes for various applications.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), you can also check out more blogs about15746-57-3
