The best catalytic activity and selectivity could be found in the prepared catalyst system with the optimum combination of the ionic liquid, nano-Pd, and support. The stabilizer is also used to prevent the aggregation of nano-Pd particles. One of the advantages of this approach is that the prereduction of catalyst is not required.

其中离子液体、奈米钯金属及担体皆有其功能，三者之组合才能达到良好之效果，同时，在合成奈米钯过程中，必须使用稳定剂以避免奈米钯金属之聚集此触媒系统之另一优点为不需先加氢还原处理，耐水性强且可重覆使用，是一种颇具潜力之选择性氢化触媒。

The thermal property studies indicate that the mass loss of compound B was 54.39% at 242.2~750℃, and when the temperature was 1000℃, there was 25.11% char residue left, which showed that the title compound has a good thermal stability and char forming capability. Using acetonitrile as the solvent instead of trichloromethane or 1, 2-dichloethane gave higher yield. During the synthesis, the yield was very low when triethylamine was used as acid acceptor alone, and when a little amount of 4-dimethylaminopyridine was added at the same time, the yield could be 81%.

结果表明，所合成的化合物B的结构与预期的结构一致；热性能研究表明，化合物B在242.2~750℃质量损失为54.39%，1000℃时仍有25.11%的炭残渣，显示出优异的热稳定性和成炭性；在相同反应条件下，用乙腈作为溶剂的反应产率比使用氯仿和二氯乙烷为溶剂的高，并且在合成过程中，单独使用三乙胺作为缚酸剂时产率很低，而当同时加入少量4-二甲氨基吡啶时，产率可达81%。
