karbodiimin
Karbodiimins are a class of organic compounds characterized by the functional group R-N=C=N-R', where R and R' are organic substituents. The central carbon atom is double-bonded to two nitrogen atoms, forming a cumulene system. This unique structure imparts significant reactivity to karbodiimins, making them valuable reagents in organic synthesis.
The most prominent application of karbodiimins is as coupling agents, particularly in the formation of amide
Beyond amide coupling, karbodiimins are employed in esterification reactions, dehydration processes, and the synthesis of heterocycles.
