Reactions of a methylzirconocene cation with phosphinoalkynes: an alternative pathway for generating Cp2Zr(II) systems.
نویسندگان
چکیده
A methylzirconocene cation (with a [B(C(6)F(5))(4)](-) counterion) transfers a methyl cation equivalent to diphenylphosphino-alkynes to generate (η(2)-alkyne)ZrCp(2) complexes bearing the [RC≡CPPh(2)Me](+) ligand. Two examples of the PMe(3) ligand stabilized [(Me(3)P)Cp(2)Zr(η(2)-RC≡CPPh(2)Me)(+)][B(C(6)F(5))(4)(-)] salts were characterized by X-ray diffraction.

Diabetes and Oxidative Stress: The Mechanism and Action
Abstract Diabetes mellitus is one of the major metabolic disorders. Diabetes is recognized for severe complications including diabetic nephropathy, neuropathy and retinopathy. Long-lasting effect of hyperglycemia results in increased oxidative stress. Oxidative stress results from an imbalance between radical-generating and radical scavenging systems. Increased oxidative stress has been shown ...

The complexation reactions between Mg2+, Ca2+, Sr2+ and Ba2+ metal cations with 15-crown-5 (15C5) were studied in acetonitrile (AN)-methanol (MeOH) binary mixtures at different temperatures using conductometric method. 15C54 forms 1:1 complexes with Mg2+, Ca2+ and Sr2+ cations in solutions. The Ma2+ cati...
متن کاملInvestigating the mRNA expression levels of Hippo pathway in adenoma polyps
Background Neoplastic adenomatous polyps generating from the epithelial cells are considered benign tumors. Adenomatous polyps are common in western countries and it can take seven to 10 or more years for an adenoma to evolve into cancer. The Hippo signaling pathway, also known as the Salvador-Warts-Hippo (SWH) pathway, is a signaling pathway that controls organ size in animals through the r...
متن کاملDirect hydrosilylation by a zirconacycle with β-hydrogen.
Azasilazirconacycle Cp2Zr{κ(2)-N(SiHMe2)SiHMeCH2} (1) and formaldehyde react through an uncatalyzed addition reaction (hydrosilylation) to form an exocyclic methoxysilyl-substituted zirconacycle. Although 1 contains 2-center-2-electron SiH groups, this transformation parallels the reactions of non-classical [Cp2ZrN(SiHMe2)2](+) ([2](+)) with carbonyls. Reactions of 1 with a series of nucleophil...
