Procedure
A total of 0.84 mole of bis(2-chloroethyl) phosphite was reacted with 1.56 moles of carbon tetrachloride in the presence of 2 mls. of triethylamine. The bis(2-chloroethyl) phosphorochloridate thus formed was reacted with 0.4 mole of resorcinol in the presence of 0.84 moles of pyridine. The procedure of Example 3 was followed in isolating a 76% yield of product which was identified by IR as tetrakis(2-chloroethyl) m-phenylene diphosphate. This product had a refractive index (nD25) of 1.5050; and, on analysis, was found to contain 28.61% chlorine and 11.85% phosphorus (as compared to theoretical calculated percentages in C14H20Cl4O8P2 of 27.31% chlorine and 11.92% phosphorus).
