nerve agent Nerve agents, sometimes also called nerve gases, are a class of organic chemicals that disrupt the mechanisms by which nerves transfer messages to organs. The disruption is caused by the blocking of acetylcholinesterase (AChE), an enzyme that ...

. Its physical properties are estimated. Soman is insoluble in water, with a boiling point of 223 degrees Celsius and a melting point of -27 degrees Celsius. Chlorosoman is at least 2.5x less toxic than its analogue. The ClG series of compounds is used more as a precursor to highly toxic compounds. For example, soman is a precursor to

Synthesis

ClGD follows the same synthetic route as soman, with fluoridation being omitted. Chlorosoman is prepared by the

Finkelstein reaction The Finkelstein reaction named after the German chemist Hans Finkelstein, is an SN2 reaction (Substitution Nucleophilic Bimolecular reaction) that involves the exchange of one halogen atom for another. It is an equilibrium reaction, but the rea ...
