PROCESS FOR THE PRODUCTION OF CYANIC ACID C,C'-[2-(6-OXIDO-6H-DIBENZ[C,E][1,2]OXA-PHOSPHORIN-6-YL)-1,4-PHENYLENE] ESTER

Cyanic acid C, C'-[2-(6-oxido-6H-dibenz[c,e][1,2]oxaphosphorin-6-yl)-1,4-phenylene] ester of formula (I) wherein R is -C≡N, is prepared by reacting the corresponding benzenediol (I, R = H) with cyanogen chloride and triethylamine in a solvent selected from acetone, butanone, butyl acetate, ethyl acetate, methyl acetate, isopropyl alcohol, toluene, diethyl ether, diethyl carbonate, acetonitrile, tetrahydrofuran, and any mixture of any of the foregoing. The process of the invention does not require a halogenated solvent or an aqueous work-up step and provides a pure, crystalline product having extremely low halogen content.
