  用格氏试剂取代硝基基团：吡啶N-氧化物的轻松酰化和烯基化

  摘要：

  用格氏试剂的芳基或烯基对硝基进行空前的取代，以适度至高收率的高化学选择性提供了2-芳基或烯基吡啶的N-氧化物。该方案允许简单且清洁地合成各种2-取代的吡啶N-氧化物和相应的吡啶衍生物。此外，还可以简单地通过连续应用两种格氏试剂来实现吡啶N-氧化物的直接一锅法迭代功能。

  The present invention relates to the use of a copolymer comprising, in polymerized form, (a) from 80 to 99.9 mol %, based on the total amount of the monomers polymerized to prepare the copolymer, of at least one monomer A which in each case comprises a heterocycle having at least 1 nitrogen atom and composed of from 3 to 10 ring members and a C 2 -C 6 -alkenyl group bonded to a carbon or nitrogen ring atom of the heterocycle; and (b) from 0.1 to 20 mol %, based on the total amount of the monomers polymerized to prepare the copolymer, of at least one monomer B copolymerizable with monomer A, said monomer B having a monoethylenically unsaturated double bond and also a linear or branched poly-C 2 -C 4 -alkylene oxide group having on average from 4 to 500 C 2 -C 4 -alkylene oxide units, in liquid and in solid detergent formulations. In addition, the invention relates to a process for preparing such a copolymer, and also to a liquid or solid detergent formulation comprising at least one such copolymer.
