As[P(NMe2)3]2+ as simultaneous ASI and PI source: Synthesis and density function calculations of planar tetracoordinate arsonium and phosphonium ions

Role change: The arsenium salt As[P(NMe2)3]2+BPh4 – (1), prepared for the first time, proved to be both an arsenic(I) and a phosphorus(I) source. Thus the reaction of 1 with [Cp2Zr(H)Cl] (Cp = eta5-C5H5) leads not only to the first arsonium ion with anti-van’t Hoff-Le Bel configuration 2a (E = As; see structure), but at the same time to the homologous phosphonium ion 2b (E = P).

Chiral bisphosphazides as dual basic enantioselective catalysts

Chiral bisphosphazides complexed with lithium salts efficiently catalyze the direct enantioselective 1,4-addition of dialkyl malonates to acyclic enones. Spectroscopic studies on the stoichiometry of the bisphosphazide and lithium salt have indicated the formation of a 1:1 species as the active enantioselective catalyst. It is suggested that the catalyst generates a complex of the protonated phosphazide and the chiral nucleophile as the key intermediate. The phosphazide moiety appears to be a promising dual basic functionality for stereo- and chemoselective catalytic transformations.

Highly enantioselective hydrogenation of alpha-dehydroamino acids by rhodium complex with H8-MonoPhos

H8-MonoPhos, a new stable and easily prepared monodentate phosphoramidite ligand, has been synthesized from H8-BINOL. The ligand showed extremely highly enantioselectivity of higher than 99.9% e.e. in the asymmetric Rh-catalyzed hydrogenation of alpha-dehydroamino acids. Our study further supports the new concept that there is no gap in efficiency and enantioselectivity between monodentate and chelating ligands for asymmetric catalysis.

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.category: chiral-phosphine-ligands, you can also check out more blogs about1608-26-0

Rhenium catalyzed sulfurization of phosphorus(III) compounds with thiiranes: New reagents for phosphorothioate ester synthesis

A new method for the mild sulfurization of phosphorus(III) compounds with thiiranes catalyzed by ReOCl3(PPh3)2 (I) or ReOCl3(SMe2)OPPh3) (II) is reported. The novel catalytic sulfur transfer reactions are rapid and occur efficiently under ambient conditions in organic solvents. This methodology enabled propylene sulfide to be used as a sulfurizing agent for the synthesis of a protected nucleotide phosphorothioate ester.

Syntheses and structural aspects of six-membered palladacyclic complexes derived from: N, N ?, N ??-triarylguanidines with N- or S-thiocyanate ligands

Six-membered palladacyclic complexes derived from N,N?,N??-triarylguanidines, [Pd{kappa2(C,N)}(mu-NCS)]2 (1-4), trans-[Pd{kappa2(C,N)}(NCS)L] (L = nitrogen based planar Lewis bases, 5-7) and cis-[Pd{kappa2(C,N)}(X)L] (L = phosphorus based conical Lewis bases, X = NCS or SCN) that contained N bound thiocyanate (8 and 10-16) and S bound thiocyanate (9) were isolated in good yields. trans-[Pd(kappa1C-guanidine)(NCS)(PMe3)2] (17 and 18) were isolated in good yields in order to understand the factors that decide the thiocyanate coordination modes in 5-16. The new complexes were characterized by analytical techniques, IR and multinuclear NMR (1H, 31P and 13C) spectroscopy and further the molecular structures of thirteen complexes were determined by single crystal X-ray diffraction. The Pd(ii) atom in 5¡¤CH2Cl2 and 6¡¤PhMe revealed a trans configuration while that in the remaining structurally characterized monomeric palladacycles revealed a cis configuration. Palladacycles 8¡¤2/3PhMe and 9¡¤MeOH represent the first pair of structurally characterized linkage isomers of organopalladium complexes to be reported. The influence of solvents on thiocyanate coordination modes in 8¡¤2/3PhMe and 9¡¤MeOH is discussed. Theoretical studies were carried out on the 8 and 9 pair and on their model complexes, 8? and 9?, and in both cases an N bound isomer was found to be more stable than their S bound counterpart by 6.14 and 4.64 kcal mol-1, respectively. In the case of methanol bridged dimers of 8? and 9?, namely 8?? and 9??, the N bound isomer (8??) is more stable by 8.11 kcal mol-1 suggesting the possible role of lattice methanol and its intermolecular interactions with 9 in the crystal lattice for the observance of a S bound thiocyanate coordination mode. The Wiberg bond index calculations were carried out on 8? and 9? which suggested the dominance of Pd ? NCS (F) and Pd ? S-CN (H) resonance forms, respectively.

Synthesis of new stable phosphorus ylides and 1,4-diionic organophosphorus compound from a reaction between hexamethyl phosphorous triamide and dimethyl acetylenedicarboxylate in the presence of CH-acids

A simple and efficient one-pot three-component reaction between hexamethyl phosphorous triamide and dimethyl acetylenedicarboxylate (DMAD) in the presence of CH-acids, such as acetylacetone, 1,3-indandione, dibenzoylmethane, anthrone, and N,N-dimethylbarbituric acid, has been studied. In all cases, new and stable phosphorus ylides are obtained in excellent yields. These stable ylides exist in solution as a mixture of two geometrical isomers as a result of restricted rotation around the carbon-carbon partial double bond, resulting from conjugation of the ylide moiety with the adjacent carbonyl group. From the reaction of N,N-dimethylbarbituric acid with DMAD in the presence of hexamethyl phosphorous triamide, a 1,4-diionic organophosphorus compound is obtained.
