What is heteroannulenes?

Answer 1

Heteroannulenes are cyclic compounds that contain one or more heteroatoms (atoms other than carbon, such as nitrogen, oxygen, or sulfur) in their ring structure, along with carbon atoms. These compounds can exhibit unique chemical and physical properties compared to their purely carbon-based counterparts, depending on the type and position of the heteroatoms. Heteroannulenes are of interest in various fields, including organic chemistry and materials science, due to their potential applications in electronics, catalysis, and pharmaceuticals.
