一种新的四膦化合物，cis，cis，cis-1，2，3，4-四（二苯基膦甲基）环戊烷（Tedicyp）与[Pd（C_3H_5）Cl]（2）配合使用，可提供一种非常有效的烯丙基胺化催化剂。在该催化剂存在下，二丙胺与乙酸烯丙酯加成反应的转化数可达980000。该络合物非常稳定，并且反应可以在水中进行而不损失活性。(C)2002由爱思唯尔科学有限公司出版
A new tetraphosphine, the cis,cis, cis-1,2,3,4-tetrakis (diphenylphosphinomethyl)cyclopentane (Tedicyp), in combination with [Pd(C3H5)Cl](2) affords a very efficient catalyst for allylic amination. A turnover number of 980 000 can be obtained for the addition of dipropylamine to allyl acetate in the presence of this catalyst. This complex is very stable and the reactions can be performed in water without loss of activity. (C) 2002 Published by Elsevier Science B.V.
