A new approach leads to the long-awaited formation of rings made of three pyrroles, which could be used to produce compounds with a host of interesting properties, and explains why they have not been ...

Quantum laws loom ever larger in physical world as new research finds quantum phenomena in effect on a molecular level. New research shows that movement of the ring-like molecule pyrrole over a metal ...

This illustration visualizes a novel electrochemical transformation in which a single carbon atom—derived from a diazo compound—is selectively inserted into the pyrrole ring via a distonic radical ...

Profs. Okujima and Uno at Ehime University, in collaboration with Prof. Kobayashi at Shinshu University, reported the selective synthesis, the molecular structure, optical properties and electronic ...

A two-step process inserts a carbon atom into the aromatic nitrogen-containing rings of pyrroles and indoles to expand them into pyridines and quinolines, respectively. The technique expands the tool ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
