多核钯（Ⅱ）－镍（Ⅱ）（1：1）酞菁对Heck反应的催化研究

Catalytic Study on Heck Reaction by Multi-nuclear Pd(Ⅱ) Ni(Ⅱ)(1:1) Phthalocyanine

使用多核钯（Ⅱ）－镍（Ⅱ）（１：１）酞菁作催化剂催化Ｈｅｃｋ反应，得到１２种较高产率的取代Ｅ－１，２－二苯乙烯、Ｅ－肉桂酸和Ｅ－甲基肉桂酸。催化剂的催化活性可与均相催化剂乙酸钯（Ⅱ）的催化活性相比。本文所用催化剂易制备且可重复使用１４次左右。

Multi-nuclear Pd(Ⅱ)-Ni(Ⅱ)(1:1) phthalocyanine was used as catalyst and char-acterlzed by ESCA,DRS and electron microscopy. With this catalyst, a series of subetiruted stilbenes,cinnamic acids and α-methylcinnamic acids was synthesized. It was found that the catalytic activity iscomparable to that of the homogeneous catalyst Pd(OAc)_2.It is easy for preparation of our catalyst andcould be reused for fourteen times with our catalyst.
