functionalized acrylate derivatives with the view to prepare functional polymers was explored. Hard zinc alkoxide generation enabled the highly chemoselective transesterification of acrylate derivatives over the undesired conjugate addition, which caused polymerization. The combined use of the catalytic zinc cluster Zn4(OCOCF3)6O and 4-(dimethylamino)pyridine delivered various functionalized acrylate derivatives
为了制备功能性聚合物,探索了一种合成功能化丙烯酸酯衍生物的实用新方法。硬锌醇盐生成使丙烯酸酯衍生物的高度化学选择性酯交换超过不希望的共轭加成,这会导致聚合。催化锌簇 Zn4(OCOCF3)6O 和 4-(二甲氨基)吡啶的联合使用通过在温和条件下将市售的丙烯酸甲酯衍生物与官能化醇进行酯交换,提供了各种官能化丙烯酸酯衍生物。
