Hydrochloric Acid → Bis(trifluoromethyl)arsane

Participants

Reaction Steps

The trifluoromethyl arsine hydrides can be made via direct reaction of the tris-trifluoromethyl arsenic iodides with zinc and hydrochloric acid. For instance, 10 g of zinc, 10 ml of water, and 15 ml of 5N HCl are shaken with 3.80 g of iodo bis-trifluoromethylarsine to give 1.03 g of bistrifluoromethylarsine (b.p. 19° C.), a 43% yield. Trifluoromethylarsine can be made by a similar method (b.p. -12.5° C.).
