Di(4-chlorophenyl) phosphite and di(4-fluorophenyl) phosphite were prepared from tris(4-chlorophenyl) phosphite and tris(4-fluorophenyl) phosphite, respectively using a previously described procedure (Walsh, E. N., Conversion of Tertiary Phosphites to Secondary Phosphonates. Diphenyl Phosphonate, J. Am. Chem. Soc. 1959, 81, 3023-6). Tris(4-chlorophenyl) phosphite was prepared from 4-chlorophenol and phosphorous trichloride with three equivalents of triethyl amine as a base using a modification of a previous procedure (McCombie, H., Saunders, B. C., Stacey, G. J., Esters Containing Phosphorus. Part I, J. Chem. Soc. 1945, 381). Similarly, tris(4-fluorophenyl) phosphite was prepared from 4-fluorophenol and phosphorous trichloride using one equivalent of triethyl amine as a base.
