Abstract (en)
[origin: WO2008098886A2] The invention relates to a method for producing (meth)acrylates (F) of N-hydroxyalkylated imidazoles by esterifying N-hydroxyalkylated imidazoles (I) with (meth)acrylic acid (S) in the presence of at least one catalyst (K) or by transesterifying it with at least one (meth)acrylic ester (D). In said formula (I), R<SUP>1</SUP> and R<SUP>2</SUP> independently represent hydrogen or C<SUB>1</SUB>-C<SUB>20 </SUB>alkyl, R<SUP>3</SUP>, R<SUP>4</SUP> and R<SUP>5</SUP> independently represent hydrogen or C<SUB>1</SUB>-C<SUB>20 </SUB>alkyl, C<SUB>1</SUB>-C<SUB>20 </SUB>alkylcarbonyl, C<SUB>2</SUB>-C<SUB>20 </SUB>alkenyl, C<SUB>2</SUB>-C<SUB>20 </SUB>alkenylcarbonyl, C<SUB>2</SUB>-C<SUB>20 </SUB>alkinyl, C<SUB>2</SUB>-C<SUB>20 </SUB>alkinylcarbonyl, C<SUB>3</SUB>-C <SUB>15 </SUB>cycloalkyl, C<SUB>3</SUB>-C<SUB>15 </SUB>cycloalkylcarbonyl, aryl, arylcarbonyl, a heterocycle or a halogen atom, and m and n are integers in the range of 0 to 20, wherein m and n cannot be 0 at the same time, and wherein the respective entities that are embraced by the variables m and n can be contained in any order, and wherein, when m = 2, the groups R<SUP>1</SUP> and R<SUP>2</SUP> are independent of each other in the respective entities.
