  • To promote greener chemical processes, particularly in pharmaceutical intermediate manufacturing.

Main Methods:

  • Investigating alternative reaction media such as aqueous biphasic systems, fluorous biphasic systems, and supercritical carbon dioxide.
  • Evaluating the potential of ionic liquids as versatile solvents for chemical reactions.
  • Focusing on atom-efficient, catalytic alternatives to stoichiometric syntheses.

Main Results:

  • Novel reaction media show promise in mitigating environmental impact.
  • Ionic liquids offer a dual solution for reducing solvent emissions and facilitating catalyst recycling.
  • Development of greener processes is essential for the pharmaceutical industry.

Conclusions:

  • Ionic liquids and other novel media are key to developing sustainable chemical processes.
  • Replacing hazardous VOCs is critical for environmental protection and regulatory compliance.
  • Efficient catalyst recycling is a fundamental requirement for economically viable and eco-friendly chemical manufacturing.
