| titleOfInvention | Method of preparing N-methylphosphonic acid diesters of acrylic and methacrylic acid amines from methylol |
| abstract | A process for the preparation of (meth)acrylamidomethylphosphonic acid diesters of formula I: n n H.sub.2 C═C(R.sub.1)--CO--N(R.sub.2)--CH.sub.2 n n --P(O)(OR 3 )(OR 4 ) (I) n is disclosed. In the above formula, R 1 is a hydrogen atom or methyl group. R 2 is a hydrogen atom, a C 1 -C 4 alkyl group (which can be substituted) or a C 3 -C 4 alkenyl group. R 3 and R 4 are each independently a phenyl group, or an alkyl group (which can be substituted) having 1-4 C atoms. Or R 3 and R 4 together form an alkylene group which forms a 5- or 7-membered ring with the oxygen atoms and the phosphorus atoms. n The process is based on reacting a N-methylol derivative of (meth)acrylamide with a phosphorous acid triester, in which a N-methylol ether of a (meth)acrylamide is used. The reaction can be advantageously catalyzed by Lewis acids. |
