Researchers have developed a new palladium-clay catalyst that has proved effective for allylic substitution reactions.

The American Chemical Society reports that subnanoscale palladium clusters on clay are able to catalyse allylation reactions.

Experts at Osaka University and the Nagoya Institute of Technology, both in Japan, have created the palladium-clay catalyst and have reported that it is more effective than alternatives because it does not require the ligands often used to stabilise palladium in the presence of oxygen.

By removing the need for the ligands, that palladium-clay catalyst was able to deliver a variety of allylated products in high yield.
