Chemists have achieved a new feat in the realm of chemical design and synthesis: They've helped create the first example of a synthetic molecule, with an asymmetric oxygen atom as its centerpiece, ...

In 1984 – the year made famous by George Orwell – I attended a physics conference in the city of Leipzig, East Germany. It was my first visit since I had been a student there 16 years before. As I had ...

The aim of the book “Oxygen atom transfer reactions” is to outline some recent developments in the studies of oxygen atom transfer mechanisms in catalytic oxidation reactions based on several ...

Heterocycles, molecular rings found in many pharmaceuticals, have a reputation for stubbornly resisting modification. That is, in a heterocycle, heteroatoms of one type aren’t easily swapped for ...

Another atom-swapping reaction has entered the ring. Yoonsu Park and his team at the Korea Advanced Institute of Science and Technology (KAIST) have devised a light-driven reaction that replaces an ...

A scheme showing two complex organic molecules with multiple ring systems: the one on the left contains a four-sided ring with an oxygen in it, and the one on the left is identical except that the ...
