ORGANOCATALYSIS, ORGANIC chemistry, SUPRAMOLECULAR chemistry, NATURAL products, and CHEMICAL reactions
Abstract: Organocatalysis is a growing area that is benefiting from advances in many fields. Its implementation has begun in areas such as supramolecular chemistry, organic chemistry and natural product synthesis. While a considerable number of important publications in the field of organocatalytic Mukaiyama‐type additions have been reported, they are yet to be fully covered in a review. Therefore, we would like to highlight the applications of various kinds of organocatalysts in Mukaiyama‐type reactions, while also including the vinylogous Mukaiyama variation. Herein we describe and discuss the development and current state of the art of the organocatalytic Mukaiyama reaction, vinylogous Mukaiyama and related reactions. [ABSTRACT FROM AUTHOR]
SOIL chemistry, WATER chemistry, SPATIAL variation, and WATERSHEDS
The article presents the study which examines the spatial and temporal variability in surface water chemistry, organic soil chemistry and hydrologic indicators at three poor-fen complexes in two boreal catchments in Northern Alberta. The examination is intended to offer insights into the dominant controls on surface water chemistry. The relation between exchangeable base saturation and potential of hydrogen (pH) of organic soils with surface water chemistry at two of the fen complexes is cited.
Five departments, one common goal:For the past 100 years, the Max‐Planck‐Institut für Kohlenforschung in Mülheim an der Ruhr has focused above all on chemical catalysis, and this is more true today than ever. Researchers in heterogeneous, homogeneous, and biocatalysis, organometallic chemistry, organic synthesis, as well as theoretical chemistry are occupied with the catalytic transformation of raw materials and pure compounds with the highest possible chemo‐, regio‐, and stereoselectivity under conditions that maximize the use of natural resources.
