To this purpose, they employed both a chemical reaction called ring-closing metathesis and photocatalysis -- a process in which chemical reactions are promoted by light energy.

A sports manufacturer has developed a plastic baseball bat from compounds created through metathesis.

Exploiting a process known as metathesis, in which carbon compounds exchange parts with one another, Grubbs showed how to create a broad range of new products, from environmentally friendly plastics to resins to pharmaceuticals.

What’s going on there is metathesis, and it’s a very common, perfectly natural process.

He found the freedom to choose his research when he joined the French Petroleum Institute in 1960, and it led to his breakthrough on metathesis.
