Synthesis, Characterization, and Reactivity of the First Osmium beta-Diketiminato Complexes and Application in Catalysis

Rosario Scopelliti, Paul Joseph Dyson, Dominique Schreiber, Andrew Douglas Phillips

The strongly chelating anionic beta-diketiminate ligand has been employed to formulate complexes involving almost every metal of the periodic table; however, the heavier metals of the d block remain relatively unexplored. This paper describes the synthesis ...

A Tunable Class of Chiral Cp Ligands for Enantioselective Rhodium(III)-Catalyzed C-H Allylations of Benzamides

Baihua Ye, Nicolai Cramer

The lack of robust and tunable chiral versions of cyclopentadienyl (Cp) ligands hampers progress in the development of catalytic asymmetric versions of a myriad of reactions catalyzed by this ubiquitous ligand. Herein, we describe of a class of chiral Cp l ...

Development of Catalytic Umpolung : Part 1: Direct Alkynylation of Heterocycles and Electron-Rich Aromatics using Alkynyl-Benziodoxolones - Part 2: Synthesis of New Bifunctional (Thio)urea-Carbene Catalysts

Jonathan Brand

The development of efficient synthetic methodologies is crucial to access complex molecules in an economic, eco-friendly and safe way. The reversal of the intrinsic reactivity of functional groups, called Umpolung, allows alternative synthetic strategies a ...

A Well-Defined Ni Pincer Catalyst for Cross Coupling of Non-Activated Alkyl Halides and Direct C-H Alkylation

Oleg Vechorkin

Carbon-carbon bond forming reactions are among the most important and useful methods for organic synthesis. During the last years, significant progress has been made in this field. Whereas many catalysts were developed for the coupling of aryl, alkenyl, an ...

Experimental and theoretical studies on the mechanism of hydrogenation by η6-arene β-diketiminato -ruthenium and -osmium complexes

Paul Joseph Dyson, Dominique Schreiber, Andrew Douglas Phillips

The β-diketiminate class of ligands is renowned for the stabilization of coordinatively unsatd. main-group and transition metal complexes. Moreover, the application and scope of transition metal β-diketiminate complexes in the catalytic transformation of o ...

Synthesis and characterisation of the water soluble bis-phosphine complex [Ru(η6-cymene)(PPh2(o-C6H4O)-κ2-P,O)(pta)]+ and an investigation of its cytotoxic effects

Rosario Scopelliti, Paul Joseph Dyson, Anna Katherine Renfrew, Christian Hartinger

Metal complexes bearing phosphine ligands are attracting increasing attention for their applications in medicinal chem. In particular, organometallic ruthenium-phosphine complexes have been found to exhibit promising antitumor activity. The synthesis, anti ...

Design, synthesis and applications of functionalized ionic liquids

Dongbin Zhao

Room temperature ionic liquids (RTILs), considered as "designers' solvents", are attracting a great attention because of their possibility to be tailored based on property requirements. The ionic liquids designed and synthesized for carrying out specified ...

New polynuclear catalysts for atom-transfer radical addition reactions

Laurent Quebatte

Homo- and heterobimetallic complexes of the late transitions metals have been synthesized by metathesis reactions of the corresponding chloro-bridged dimers. These reactions have the advantage of being fast and giving rise to structurally defined products ...

A bimetallic ruthenium ethylene complex as a catalyst precursor for the Kharasch reaction

Laurent Quebatte, Kay Severin, Euro Solari

A bimetallic complex, in which a RuCl2 (eta(2)C(2)H(4))(PCy3) fragment is connected via three chloro, bridges to a (eta(6)-p-cymene)RuCl2 fragment, has been synthesized and characterized by single-crystal X-ray crystallography. This complex was used to cat ...
