Filed:

Nov 29, 1974

Appl. No.:

5/528300

Inventors:

Assignee:

Chevron Research Company - San Francisco CA

International Classification:

C07F 924

US Classification:

260984

Abstract:

O,S-dimethyl phosphoroamidothioates are prepared by reacting in the liquid phase methyl phosphorodichloridite with methyl sulfenyl chloride in the presence of a lower alkanoic acid to produce O,S-dimethyl phosphorochloridothioate and subsequently reacting in the liquid phase the O,S-dimethyl phosphorochloridothioate with ammonia or an amine.
