N-Chlorosuccinimide (NCS) is the organic compound with the formula C2H4(CO)2NCl. This white solid is used for chlorinations. It is also used as a mild oxidant. NCS is related to succinimide, but with N-Cl in place of N-H. The N–Cl bond is highly reactive, and NCS functions as a source of "Cl".
Synthesis and selected reactions
NCS is produced from succinimide by treatment with Cl sources, such as sodium hypochlorite (bleach), and t-butylhypochlorite, and even chlorine.
Electron-rich arenes are readily monochlorinated by NCS. Aniline and mesitylene are converted to the respective chlorinated derivatives.
