Chemical compound

Diphenylchloroarsine (DA) is the organoarsenic compound with the formula (C6H5)2AsCl. This odorless, toxic liquid was once used as harassing agent. It is also an intermediate in the preparation of other organoarsenic compounds. The molecule consists of a pyramidal As(III) center attached to two phenyl rings and one chloride.

Uses

Diphenylchlorarsine was first used as a chemical weapon on the Western front during the trench warfare of World War I It belongs to the class of chemicals classified as vomiting agents. Other such agents are diphenylcyanoarsine (DC) and diphenylaminechlorarsine (DM, adamsite).

It is a useful reagent in the preparation of other diphenylarsenic compounds, e.g. by reactions with Grignard reagents:

RMgBr + (C6H5)2AsCl → (C6H5)2AsR + MgBrCl
(R = alkyl, aryl)

Safety

Diphenylchlorarsine is known to cause sneezing, coughing, headache, salivation, and vomiting. China and Japan are negotiating remediation of stocks of a variety of organoarsenic weapons stored in northeastern China including chlorodiphenylarsine.
