chemoselective transfer hydrogenation of α,β-unsaturated carbonyls using immobilized palladium metal-containing ionic liquid as a versatile heterogeneous catalyst with an excellent conversion and chemoselectivity (up to 100 %). The influence of various reaction parameters such as the effect of hydrogen donor, solvent, temperature, and time were studied. The catalyst was recycled for four consecutive cycles without
这项工作报告了一种简单高效的 α,β-不饱和羰基化学选择性转移氢化方案,使用固定化含钯金属离子液体作为多功能多相催化剂,具有出色的转化率和化学选择性(高达 100%)。研究了氢供体、溶剂、温度和时间等各种反应参数的影响。催化剂连续循环四次,催化活性没有明显损失。由于使用 HCOONH4 作为氢源、温和的反应条件和简单的后处理程序,开发的方案更具优势,适用于广泛的底物。图形摘要
