Procedure

Aniline (182 g, 1.95 mol) was added over 30 min via an additional funnel to an ice-cold aqueous solution of hypophosphorus acid (50% wt, 258 g, 1.95 mol). The light brown solution turned into thick slurry. Acetone (500 ml) was added and the resulting mixture was stirred for 5 min before filtration. The solid was washed with acetone to provide the product anilinium hypophosphite (134 g, 43%).
