Cyclophane Chemistry: Synthesis, Structures and Reactions

WebCyclophane. A cyclophane is a hydrocarbon consisting of an aromatic unit (typically a benzene ring) and an aliphatic chain that forms a bridge between two non-adjacent positions of the aromatic ring. More complex derivatives with multiple aromatic units and bridges forming cagelike structures are also known. WebJul 29, 2015 · A general classification of cyclophanes is as follows: [ n ]orthocyclophane, [ n ]metacyclophane, and [ n ]paracyclophane ( 1–3) ( Figure 1 ). The prefixes represent the position of the attachment to an aromatic system while [ n] represents the number of methylene groups present in the aliphatic bridge. darwin food
