Isocyanides are organic compounds characterized by the functional group -N≡C, where a nitrogen atom is triple-bonded to a carbon atom. They are known for their distinctive and often unpleasant odors. Isocyanides are used in various chemical reactions, particularly in the synthesis of pharmaceuticals and agrochemicals. These compounds can be toxic and are handled with care in laboratory settings. Isocyanides can react with a variety of nucleophiles, making them valuable intermediates in organic synthesis. Their unique reactivity allows chemists to create complex molecules, contributing to advancements in fields like medicinal chemistry and materials science.
