Abstract (en)
[origin: WO2008098885A1] The invention relates to a method for producing (meth)acrylic esters (F) of N-hydroxyalkylated lactams (L) by esterifying annular N-hydroxyalkylated lactams (L) with (meth)acrylic acid (S) in the presence of at least one metal salt of C<SUB>1</SUB>-C<SUB>10</SUB> alkanolates (A) or transesterifying it with at least one (meth)acrylic ester (D) by adding the metal salt of C<SUB>1</SUB>-C<SUB>10</SUB> alkanolates (A), which is used as the catalyst, in the absence of solvents and completely at the start of the reaction. In said formula (L), R<SUP>1</SUP> represents C<SUB>1</SUB>-C<SUB>5</SUB> alkylene or C<SUB>2</SUB>-C<SUB>20</SUB> alkylene, interrupted by one or more oxygen and/or sulfur atoms and/or one or more substituted or unsubstituted imino groups and/or by one or more cycloalkyl-, -(CO)-, -O(CO)O-, -(NH)(CO)O-, -O(CO)(NH)-, -O(CO)- or -(CO)O groups, wherein the mentioned groups can be substituted by aryl, alkyl, aryloxy, alkyloxy, heteroatoms and/or heterocycles, with the proviso that R<SUP>1</SUP> must not comprise any atom other than a carbon atom directly adjacent to the lactam carbonyl group. R<SUP>2</SUP> represents C<SUB>1</SUB>-C<SUB>20</SUB> alkylene, C<SUB>5</SUB>-C<SUB>12</SUB> cycloalkylene, C<SUB>6</SUB>-C<SUB>12</SUB> arylene or C<SUB>2</SUB>-C<SUB>20</SUB> alkylene, interrupted by one or more oxygen and/or sulfur atoms and/or one or more substituted or unsubstituted imino groups and/or by one or more cycloalkyl-, -(CO)-, -O(CO)O-, -(NH)(CO)O-, -O(CO)(NH)-, -O(CO)- or -(CO)O groups, wherein the mentioned groups can be substituted by aryl, alkyl, aryloxy, alkyloxy, heteroatoms and/or heterocycles, or R<SUP>2</SUP>-OH represents a group of the formula -[X<SUB>i</SUB>]<SUB>k</SUB>-H, k is a number of 1 to 50 and Xi for any i = 1 to k can be independently selected from the group including -CH<SUB>2</SUB>-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-CH<SUB>2</SUB>-N(H)-, -CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-N(H)-, -CH<SUB>2</SUB>-CH(NH<SUB>2</SUB>)-, -CH<SUB>2</SUB>-CH(NHCHO)-, -CH<SUB>2</SUB>-CH(CH<SUB>3</SUB>)-O-, -CH(CH<SUB>3</SUB>)-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-C(CH<SUB>3</SUB>)<SUB>2</SUB>-O-, -C(CH<SUB>3</SUB>)<SUB>2</SUB>-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-CHVin-O-, -CHVin-CH<SUB>2</SUB>-O-, -CH<SUB>2</SUB>-CHPh-O- und -CHPh-CH<SUB>2</SUB>-O-, wherein Ph represents phenyl and Vin represents vinyl.
