Abstract

Intermolecular coupling reactions of 1, 3-dienes and aldehydes via transmetalation of nickelacycle intermediate with i Bu2Al-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 π-allynickel forms.
