| titleOfInvention | Process for preparing secondary phosphane oxides |
| abstract | For the production of secondary phosphine oxides of the general formula in which R¹ and R² are the same or different and are an alkyl radical having 1 to 18 carbon atoms, a cycloalkyl or a phenyl radical, an alkane or arane-phosphonous monoester of the general formula is used in which R³ is identical or different to R¹ and has the same meaning as R¹ and R² in formula I, with a Grignard compound of the general formula R²MgX (III) in which R² has the meaning given above and X represents a Cl, Br or I atom, at temperatures -30 and + 20 ° C in the presence of tetrahydrofuran. The phosphonous acid monoester (II) is introduced, 1.1 to 1.5 mol of the Grignard compound (III), dissolved in tetrahydrofuran, are introduced into the initial charge per mol of this ester, with cooling, the reaction product is hydrolyzed with the aid of phosphoric acid and separates the secondary phosphine oxide from the hydrolyzate. |
