Abstract:
Ni(II) norcorroles have garnered significant attention due to their distinct antiaromaticity and stability. However, their conventional synthetic protocol requires the use of unstable Ni(0) complexes, resulting in cumbersome procedures and a limited substrate scope. Herein, we disclose an efficient method for the synthesis of Ni(II) norcorroles using manganese powder. This improved protocol affords Ni(II) norcorroles with heteroaryl and halogenated aryl substituents at the meso positions with a simplified isolation procedure.

Dehydration Synthesis
Dehydration synthesis (also called a condensation reaction) is the chemical process in which two molecules covalently link together to form a new molecule, along with the release of a water molecule. Many physiologically important compounds form by dehydration synthesis reactions, such as complex carbohydrates, proteins, DNA, and RNA.
