172 g (0.852 mol) of diphenylphosphine oxide and 0.8 g of indium chloride are mixed and heated to 152° C., the pressure being reduced simultaneously (8 mbar). Diphenylphosphine distills off through a descending condenser at a transition temperature of 132° C. After a total of 2 hours, the internal temperature has been raised to 195° C. 70 g of diphenylphosphine are obtained. That corresponds to a yield of 88% of theory.
