In news- The 2021 Nobel Prize in Chemistry was awarded to German scientist Benjamin List and Scotland-born scientist David WC MacMillan “for the development of asymmetric organocatalysis.” 

About the research-

  • They developed a new and ingenious tool for molecule building- organocatalysis. 
  • Researchers long believed that there were just two types of catalysts available: metals and enzymes.
  • Independently of each other, laureates Benjamin List and David MacMillan developed a third type – asymmetric organocatalysis – which builds upon small organic molecules.

  • Organic catalysts have a stable framework of carbon atoms and more active chemical groups can be attached to them. 
  • They contain elements such as oxygen, nitrogen, sulphur or phosphorus, meaning that they are both environmentally friendly and cheap to produce.
  • The increased use of organic catalysts is due to their ability to drive asymmetric catalysis. 
  • Whenever molecules are being built, two different molecules can form and chemists would want to use any one of them when producing pharmaceuticals. 
  • Both Benjamin List and David MacMillan have demonstrated how organic catalysts can be used to drive multitudes of chemical reactions. 
  • With the help of these reactions, chemists can now produce anything ranging from new pharmaceuticals to molecules that can capture light in solar cells.
