研究了镍配合物中间体与（Bu_2Al）-B-i-acac的金属转移反应，得到了1，3-二烯和醛的分子间偶联反应。在反应中，线性加合物或支链加合物产生，这取决于1，3-二烯和醛的性质，通过两个镍环，这是相对稳定的四种可能的镍环，因为与π-烯丙基镍形式的平衡。
Intermolecular coupling reactions of 1,3-dienes and aldehydes via transmetalation of nickelacycle intermediate with (BU2Al)-B-i-acac were investigated. In the reactions, a linear adduct or a branched adduct was produced, depending upon the nature of 1,3-dienes and aldehydes, via two nickelacycles that were relatively stable among the four possible nickelacycles because of the equilibrium with pi-allynickel forms.
