Preparation,Characterization and Catalytic Performance of Ethylenediamine-2-Pyridinecarbaldehyde Schiff Base Palladium Complex

利用2-吡啶甲醛和乙二胺制得乙二胺-2-吡啶甲醛席夫碱配体,再与钯盐作用制得乙二胺-2-吡啶甲醛席夫碱钯配合物.运用红外光谱、核磁共振、质谱、元素分析、ICP等分析手段对乙二胺-2-吡啶甲醛席夫碱配体及其钯配合物进行了表征,提出了乙二胺-2-吡啶甲醛席夫碱钯配合物的结构,并对其在Heck反应中的催化性能进行了研究.

Ethylenediamine-2-pyridinecarbaldehyde schiff base ligand was prepared by the condensation reaction of ethylenediamine with 2-pyridinecarbaldehyde, then ethylenediamine-2-pyridinecarbaldehyde schiff base palladium complex was synthesized by the reaction of ethylenediamine-2-pyridinecarbaldehyde schiff base with Li2PdC14 in methanol. The structures of ethylenediamine-2-pyridinecarbaldehyd schiff base ligand and its palladium complex were characterized by FT-IR, NMR, MS, the elemental analysis and ICP. Catalytic performance of the palladium complex was studied in Heck reaction.
