  • Elegant experiments with light

    Scientists of the department of Homogeneous Catalysis have found a new elegant way to make use of photoredox catalysis. Researchers of the Max-Planck-Institut für Kohlenforschung have expanded the molecular toolbox for efficient, targeted syntheses: To do so, they use a very special catalyst - and t more

  • Novel method for controlling chemical reactions discovered

    Substituted aromatics are among the most important building blocks for organic compounds such as drugs, crop­protecting agents, and many materials. The function of the molecules is determined by the spatial arrangement of the different building blocks, the substitution pattern. A research team from more

  • Enzyme-metal-single-atom hybrid catalysts for efficient one-pot chemoenzymatic reactions

    The merging of different types of catalysis including enzymatic, homogeneous, and heterogeneous catalysis is fundamentally important for both understanding catalysis at the atom level and the design of novel hybrid catalysts. The latter points to a direction toward the ideal catalyst that can drive more

Making Reactions Faster

How different factors can affect how quickly a reaction happens is a common topic in the chemistry curriculum. This graphic serves as a convenient summary for teachers and students alike of what these different factors are, and how and why they affect the rate of a reaction. However, it’s not only o more

  • Water instead of mineral oil

    Optical active substances made from chiral catalysis form the basis of many drugs. Expensive precious-metal catalysts are required for the chemical production, which due to their thermal instability decompose at high temperatures and can therefore only be used once. The innovative process of DexLeChem GmbH makes it possible for the first time to use these precious-metal catalysts made from rhodium, ruthenium or iridium more than once, without modifying them. At the same time, reaction occurs in aqueous solutions instead of mineral-oil-based solvents, which increases the sustainability of the process. This is a milestone in catalysis and a real opportunity for the pharmaceutical industry. more

  • Light plus current: The formula for researching what happens to individual nanoparticles

    A combination of dark-field microscopy and electrochemistry can make individual nanoparticles in a liquid medium visible. The technique is suited to determine the activity of catalysts during their use. more

  • Customized ligands pave the way for new reaction pathways

    For the first time, an efficient catalyst for palladium-catalyzed C–C bonding between aryl chlorides and alkyl lithium compounds has been found. This reaction enables simpler synthesis routes for important products, such as pharmaceuticals, while avoiding much salt waste. more
