Abstract

1,138,815. Cyclic phosphorus derivatives. FARBENFABRIKEN BAYER A.G. 18 Feb., 1966 [22 Feb., 1965; 5 Oct., 1965], No. 7322/66. Heading C2C. Novel phosphonic and thiophosphonic acid derivatives of the general formula where R is C 1-4 alkyl, cyclohexyl, or aryl, X is oxygen or sulphur and ZH and YH, alike or different, are -OH, -SH, or -NH-alkyl, wherein the alkyl radical contains from 1 to 4 carbon atoms, are prepared by reacting an appropriate phosphonic or thiophosphonic acid dihalide with a 1,2-disubstituted ethane of the formula HY-CH 2 -CH 2 -ZH in an inert, anhydrous organic solvent, optionally in the presence of a tertiary organic base. The reaction temperature is normally from about 0‹ to 150‹ C., preferably from 20‹ to 80‹ C., and the reaction time is from 1 to 12 hours, preferably from 2 to 6 hours. The compounds are useful as catalysts in the conversion of organic isocyanates into carbodiimides, and the preparation of diphenyl carbodiimide from phenyl isocyanate is described.
