Abstract
Disclosed is a method for producing, from an aqueous basic composition, a primary arsine having one hydrocarbyl group bonded directly to As, the basic composition having been obtained from the combination of components comprising an alkali metal arsenite and a reactive hydrocarbyl halide by combining the aqueous composition with an acidic, nascent hydrogen-generating reducing agent to produce the primary arsine directly from the aqueous composition without isolation of the primary arsonic acid intermediate.
