Abstract:
The present invention relates primarily to a process for producing particular phosphinates (phosphonous acid monoesters) and use thereof for producing biologically active substances which may be used in the pharmaceutical or agrochemical sector, preferably for producing phosphorus-containing amino acids.

Claim (Index 1):
Process for producing a compound of formula (I) comprising reacting a compound of formula (II) with a compound of formula (III)\n R 2 \u2014OH \u2003\u2003(III) \n wherein in each case: R 1  represents (C 1 -C 12 )-alkyl, (C 1 -C 12 )-haloalkyl, (C 6 -C 10 )-aryl, (C 6 -C 10 )-haloaryl, (C 7 -C 10 )-aralkyl, (C 7 -C 10 )-haloaralkyl, (C 4 -C 10 )-cycloalkyl or (C 4 -C 10 )-halocycloalkyl, R 2  represents (C 3 -C 12 )-alkyl, (C 3 -C 12 )-haloalkyl, (C 6 -C 10 )-aryl, (C 6 -C 10 )-haloaryl, (C 7 -C 10 )-aralkyl, (C 7 -C 10 )-haloaralkyl, (C 4 -C 10 )-cycloalkyl or (C 4 -C 10 )-halocycloalkyl, R 3  and R 4  each independently of one another represent methyl or ethyl, in the presence of an acidic catalyst and in the presence of water.
