A method was developed for the preparation of primary and secondary alkyl- and aryl-haloarsines; an alkyl- or aryl-(2-chlorovinyl)arsine is split by means of alkali, and the resulting organoarsenic oxide is then treated with hydrochloric acid. The method is general, and it makes it possible to prepare various haloarsines, including some that cannot be prepared by Meyer's reaction. In particular, dichloroisopropyl-, butyldichloro-, dichloro-isopentyl-, and dichlorostyryl-arsines can be prepared in satisfactory yields.
