Abstract
A comprehensive review of the reports in the literature concerning conjugation of polyunsaturated acid and their esters (vegetable oils such as: linseed oil, sunflower oils, rape oil, soybean oil; linoleic acid, methyl linoleate etc.) catalyzed by supported transition metals and their complexes is presented. The following issues are analyzed: chemo-, regio-, and stereoselectivity of the double bond migration in polyenes, mechanism of conjugation and accompanying isomerization process, hydrogenation and E-Z isomerization, stability of homo- and heterogenous catalysts, removal of catalysts from the post-reaction mixture, and possibility of catalysts recycling.
Keywords: Polyunsaturated Acids, Transition Metals, vegetable oils, linseed oil, sunflower oils, rape oil, hydrogenation, E-Z isomerization

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
Chemistry and Biology of Carbohydrates
Carbohydrates are one of the most abundant natural products and are considered to be extremely important biomolecules for their ever-increasing impact on chemistry and biology. Their role in several important biological processes, notably energy storage, transport, modulation of protein function, intercellular adhesion, malignant transformation, signal transduction, viral, and bacterial cell ...read more
