Various methods for the synthesis of bimetallic complexes, in which two different metal fragments which are connected by two or three halogeno bridges, are reported. The reactions are usually fast and give rise to structurally defined products in quantitat ...
An efficient and concise total synthesis of (+)-lentiginosine (1) starting from an L-tartaric acid-derived nitrone using organometallic addition, indium-catalyzed reduction, and ring-closing metathesis reaction as the key steps is reported. Structural anal ...
A review. Only the most important methods for the generation of organometallic reagents and intermediates are covered in this review. This holds for the reductive insertion of Li into org. halides, the permutational interconversion of org. halides with org ...
The search of new energy sources has motivated during the last few years numerous research projects due to environmental, economical and political reasons. One of the main subjects of these works is the development of fuel cells. Within this framework the ...
The question is addressed of whether the triruthenium cluster cation Ru-3(mu(2)-H)(3)(eta(6)C(6)H(6))(eta(6)-C6Me6)(2)(mu(3)-O), 1, is a supramolecular, outer-sphere benzene hydrogenation catalyst or is 1 a precatalyst to well-known Ru(0)(n) catalysis ...
Transition-metal centers are the active sites for a broad variety of biological and inorganic chemical reactions. Notwithstanding this central importance, density-functional theory calculations based on generalized-gradient approximations often fail to des ...
The first part of this work deals with oxidative addition reactions of the triangulo platinum cluster [Pt3(μ-CO)3(PCy3)3]. Reactions with the electrophilic molecules ICH2CN and X2 (X = I and Br) and with the weakly polar reagent Ph3SnH have been studied. A ...
In many microorganisms, flux limitations in oxidative metab. lead to the formation of overflow metabolites even under fully aerobic conditions. This can be avoided if the specific growth rate is controlled at a low enough value. This is usually accomplishe ...
As a further test of the concept of regioexhaustive functionalization, 2-chloro-6-(trifluoromethyl)pyridine, 2-chloro-5-(trifluoromethyl)pyridine and 3-chloro-4-(trifluoromethyl)pyridine were each converted into the three possible carboxylic acids. This wa ...
A review with refs. concerning electrochem. oxidn. of orgs. in aq. media on iridium oxide and synthetic diamond based electrodes is presented. Effect of nature of electrode material influence on selectivity and efficiency of this process is considered. The ...
