Synthetic organic and "green" chemistry

Recently, the call for "sustainable developments", reduction of CO2-emission and environmentally friendly technologies has led to an increasing interest in Green Chemistry. Photochemistry can serve as a valuable green chemical application since light is regarded as a clean reagent. However, despite obvious advantages in terms of selectivity and sustainability, the photochemical production of chemicals on industrial scales remains rare. To overcome this neglect, we are studying selected photochemical reactions with moderately concentrated sunlight. Furthermore, we are investigating photochemical transformations for the construction of complex heterocycles which may be useful as future pharmaceuticals or agrochemicals. Current research projects include:

  1. Solar chemical production of versatile fine chemicals with sunlight [1,4].
  2. Photochemical cyclization reactions of amino acids and (poly)peptides [2, 3, 5].
  3. Photochemical alternatives to existing thermal reactions (Grignard, Friedel-Crafts, Jones reactions etc.) [1-5].
