Abstract
Novel tertiary phosphine oxides containing in one radical at least two hydroxy groups or functional derivatives thereof are obtained by adding olefins having at least two hydroxy groups or functional derivatives thereof to secondary phosphine oxides at elevated temperatures in the presence of a free radical generator. The products are useful as flame-retardant agents and intermediates for anti-corrosive agents and pesticides.
