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 ...
Hydrogen holds the potential to be an alternative to replace fossil fuels in the future. The tremendous research effort dedicated to the issue of hydrogen storage has led to considerable advancements in the development of both adsorption materials and chem ...
A new catalytic procedure for atom-transfer radical addition (ATRA) and cyclization (ATRC) reactions is described. The combination of the ruthenium(III) complex [RuCl2Cp*(PPh3)] with magnesium allows these reactions to be performed under mild conditions wi ...
The increasing progress in medicinal chemistry and chemical biology requires more versatile synthetic strategies for the generation of libraries of active compounds and theirs analogues. A wide range of biologically active natural and synthetic compounds c ...
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 ...
The water soluble ruthenium(II) complex [RuCl2(PTA)([9]aneS3)] (PTA = 1,3,5-triaza-7-phosphadamantane, [9]aneS3 = 1,4,7-trithiacyclononane) catalyzes the hydrogenation of CO2 and bicarbonate in aqueous solution. ...
Sequential enyne cross-metathesis reactions of arylalkynes with ethylene followed by atom transfer radical addition (ATRA) with ethyl dichloroacetate or dichloroacetonitrile provide 1,5-dichloropent-2-ene derivatives. The second-generation Grubbs alkyliden ...
Certain ruthenium complexes are potent catalysts for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions, in particular if they are used in conjunction with reducing agents such as magnesium. This short overview summarizes recent develop ...
The catalytic activity of [Cp*OsBr2(PPh3)] in conjunction with Mg has been evaluated for atom transfer radical addition (ATRA) and cyclization (ATRC) reactions. The Os complex enabled these reactions to be performed with similar efficiency as that of the a ...
Abstract: Activated cyclopropanes, such as vinyl and carbonyl cyclopropanes, are useful building blocks in organic chemistry due to their exceptional reactivity. This review focuses on the use of cyclopropyl carbonyls and imines in cyclization and cycloadd ...
