# New reaction moves nitrogen atom around pyridine ring

Researchers report a method to isomerize pyridine by shifting the nitrogen atom to different positions on the ring. This enables access to otherwise difficult-to-make pyridine isomers, which are important in pharmaceuticals and materials science. The catalytic process offers a new strategy for modifying nitrogen-containing aromatic compounds.

**Importance:** 3/5
