Complex molecules, consisting of many atoms chemically bonded together, may have atoms arranged linearly or in rings.Heterocyclic and homocyclic compounds are examples of molecules in which the constituent atoms form rings. The cyclic portion of the...

A ring compound, also called a cyclic compound, is one whose molecules contain atoms chemically bonded together to create a closed chain or circle. Generally, such molecules are organic, and so the ring configuration is composed of carbon atoms. Ring...

These have a ring structure with at least one ring carbon replaced. The most common contain oxygen or nitrogen. About half of all natural compounds are heterocyclic and can be aliphatic or...

Heterocyclic compounds are organic compounds that contain a ring structure containing atoms in addition to carbon, such as sulfur, oxygen or nitrogen, as part of the ring. They may be either simple aromatic rings or non-aromatic rings. Some examples are...

Chemistry of Heterocyclic Compounds (Studies in Organic Chemistry, 35). Edited by J. Kovac and P. Zalupsky (Elsevier Science Publishing Co., Inc., Box 1663, Grand Central Station, New York 10163, U.S.A. 1988. As the editors aptly note in the preface, heterocyclic chemistry, once dependent...

ABSTRACT: This study describes the degradation of nitrogen-heterocyclic compounds (NHCs) by anodic oxidation and electro-Fenton. Using indole as a model nitrogen-heterocyclic compound, the removal of indole reached 68% and 97% by anodic oxidation and electro-Fenton, respectively, while the decay of TOC was 15%...
