Process for preparing cyclic phosphinic acid esters

Process for preparing cyclic phosphinic acid esters of the formula (I) STR1 wherein R1 is an alkyl radical having up to 18 carbon atoms or a phenyl radical being optionally substituted by alkyl, halogen or alkylated amino groups, R2 stands for a hydrogen atom or has the same meaning as R1 and n is 1 or 2, which comprises reacting phosphinic acid monoesters of the formula (II) STR2 wherein R3 is an alkyl radical having up to 8 carbon atoms optionally substituted by chlorine atoms and R1 has the meaning given above, with an alkenol of the formula (III) STR3 wherein R2 and n have the aforesaid meaning, in the presence of catalytic quantities of free radical forming agents, splitting off the alcohol of formula (IV) simultaneously or subsequently and separating the reaction products, preferably by distillation.
