• Reusable catalyst makes C–H bond oxidation using oxygen easier and more efficient
  

  In the chemical industry, the selective cleavage and oxidation of carbon–hydrogen (C–H) bonds, called “oxidative C–H functionalization” is an essential step in the production of many solvents, polymers, and surfactants, as well as intermediate compounds for agrochemicals and pharmaceuticals. Ideally more

• Sometimes less is more
  

  The harder you pull, the quicker it goes. At least, that used to be the rule in mechanochemistry, a method that researchers apply to set chemical reactions in motion by means of mechanical forces. However, as chemists led by Professor Dominik Marx, Chair of Theoretical Chemistry at the Ruhr-Universi more

• Bonds going for gold!

  Rai-Shung Liu and co-workers at the National Tsing-Hua University, in Hsinchu, have reported a gold-catalysed procedure for the oxidative cleavage of aryl-substituted alkynyl ethers using molecular oxygen. ‘This work serves the first example that a C-H, single and triple carbon-carbon bonds can be more
