| Popis | Contemporary technological development bears benefits for the development of increasing population and at the same time poses threats to the mankind and Earth if it will not be combined with already formulated coincident strategy of sustainable development on global scale which has no alternative. Entering the Third Millennium, scientists and engineers are given crucial role in its implementation which should be reflected in their approaches to solutions of problems. These approaches are defined for synthetic chemists and production engineers as the principles of so-called Green Chemistry or Sustainable Chemistry (SusChem). These principles may be characterized generally as environmentally friendly and discrete to resources of raw materials and energy, i. e. an application of alternative synthetic pathways and reaction conditions, formations and application of minimal toxic and hazardous intermediates and products, and maximum utilization of raw materials and energy inputs. Catalysis (e. g. by transition metal complexes, micellar, PTC, solid support), sonochemistry, microwave assisted syntheses, non-classical solvent application, and also sophistic approach to reaction planning and process design are the often used methods of Green and Sustainable Chemistry. This contribution will be demonstrate a sophistic approach to preparation of two different pure products from the very same kit of reagents on two examples reactions cyanide anion with 2,4-dichlorobenzyl chloride and benzoyl chloride, respectively (Scheme). All synthesized products were prepared under different reaction conditions in very high yields (more than 90%). |
