Platinum(II), palladium(II), and nickel(II) thiosalicylate complexes

A series of platinum(II), palladium(II) and nickel(II) complexes containing thiosalicylate ligands have been prepared by the reaction of [MX2L2] complexes [X = halide or acetate; L or L2 = ancillary neutral donor ligand such as a tertiary phosphine or cycloocta-1,5-diene (cod)] with thiosalicylic acid in methanol with added pyridine. Displacement of the cod ligand from [Pt(SC6H4CO2)(cod)] with phosphines and phosphites allows the synthesis of additional derivatives. The complexes [Pt(SC6H4CO2)(PPh3)2] and [Ni(SC6H4CO2)(dppp)] [dppp = 1,3-bis(diphenylphosphino)propane] have been the subjects of single-crystal X-ray diffraction studies. While both complexes contain the expected approximately square-planar metal co-ordination environments, the plane of the thiosalicylate ligand is inclined at an angle of 45.9 to the platinum co-ordination plane, but at only 9.4 to the nickel plane. The results of an electrospray mass spectrometry study of the thiosalicylate complexes and some related thioglycolate, 2-sulfanylpropionate and salicylate derivatives are discussed in terms of the stabilities of the complexes.

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.Formula: C34H28Cl2FeP2Pd, you can also check out more blogs about72287-26-4

One-pot, two-step synthesis and photophysical properties of 2-(5-phenylindol-3-yl)benzimidazole derivatives

An efficient one-pot, two-step procedure has been successfully applied for the synthesis of a series of 2-(5-phenylindol-3-yl)benzimidazoles. The first step was cyclocondensation-oxidation of 5-bromoindole-3-aldehydes with o-phenylenediamines in 1,4-dioxane, which was promoted by activated carbon and used atmospheric air as a “green” oxidant. The resulting 2-(5-bromoindol-3-yl)benzimidazoles in the pot were in situ coupled with postadded phenylboronic acids, and catalyzed with PdCl2(dppf) in 1,4-dioxane-H2O to afford the desired compounds with satisfactorily high yields. The relationship between the synthesized compounds’ absorption, and fluorescence spectra with molecular structures has been investigated with experimental data and theoretical calculations.

Stereoselective synthesis of a pivotal chiral intermediate for natural salicylic macrolides

As a part of our ongoing research projects on the synthesis of natural salicylic macrolides, the optically active protected salicylate bearing the chiral diene substituent was required as a pivotal synthetic intermediate. The synthesis of the compound was achieved with a high optical purity starting from D-mannitol through Heck coupling reaction and terminal methylenation as key C-C bond forming reactions.

Structural Characterization of Heterodimetallic Zr/Pd and Zr/Rh Catalyst Precursors Containing the C5H4PPh2 Ligand

(Cp-PPh2)2ZrCl2 (5) reacts with (PhCN)2PdCl2 to yield the early-late heterodimetallic complex [(Cp-PPh2)2ZrCl2/PdCl2], 7, which was characterized by an X-ray crystal structure analysis. The phosphine-substituted bent metallocene moiety in 7 serves as a conformationally flexible chelate phosphine ligand (angle P-Pd-P: 96.46(3)). Complex 7 is an active catalyst for the cross-coupling of sec-butylmagnesium bromide with bromobenzene, leading to excellent regioselectivity and moderate reactivity. Complex 5 reacts with dicarbonylrhodium chloride dimer (0.5 equiv) to yield the triply bridged complex 12, [ClZr(mu-Cp-PPh2)2-(mu-Cl)Rh(CO)Cl], which was also characterized by X-ray diffraction (the angle P-Rh-P is 158 at the distorted square-pyramidal pentacoordinated rhodium center). (Cp-PPh2)2Zr-(CH3)2 (13) reacts with [H(CO)Rh(PPh3)3] (14) with loss of two PPh3 ligands and instantaneous liberation of methane to form complex 15, [CH3Zr(mu-Cp-PPh2)2Rh(CO)PPh 3](Zr-Rh), which probably contains a metal-metal bond between the early and late transition metal. Complex 15 is a very active 1-hexene hydroformylation catalyst (TOF > 600, n/iso ? 3 at 80C).

Total synthesis of kendomycin: A macro-C-glycosidation approach

Kendomycin, also known as (-)-TAN 2162, is a novel polyketide-derived ansamycin isolated from Streptomyces sp., which exhibits potent antagonist and agonist activities at the endothelin and calcitonin receptors, respectively. This bacterial metabolite also possesses a strong antibiotic activity against a range of gram-positive and -negative bacteria and cytostatic effects on the growth of human cancer cell lines. When a novel macroglycosidation reaction is employed as the key step, the first enantioselective total synthesis of kendomycin has been accomplished. A Friedel-Crafts-type ring closure of the acyclic precursor containing tetrahydropyran and benzofuran moieties produces the macrocycle as a single stereoisomer in good yield, thus establishing the aryl C-glycosidic linkage of the ansa core. This reaction requires a phenolic glycosyl acceptor and appears to proceed through a rapid O-glycosidation followed by a slow rearrangement to an aryl C-glycoside. The requisite secomacrocycle is prepared by the Pd(0)-catalyzed B-alkyl Suzuki-Miyaura cross-coupling of two subunits, which in turn can be expeditiously assembled from readily available building blocks in a modular fashion.
