An imine is a type of organic compound that contains a carbon-nitrogen double bond (C=N). It is formed when a carbonyl compound, such as an aldehyde or ketone, reacts with an amine. This reaction typically involves the removal of a water molecule, making imines important in various chemical synthesis processes. Imines can be found in many natural and synthetic compounds, playing a crucial role in fields like medicinal chemistry and organic synthesis. They can also undergo further reactions, such as hydrolysis, to regenerate the original carbonyl compound and amine, showcasing their versatility in chemical reactions.
