In a nickel-promoted cyclization, 1,3-diene can serve as a ligand and it affects the reaction course. A s-cis conformation of 1,3-diene is necessary for coordination to the metal, and the highest selectivity () was obtained in the reaction of 1b with hydride nickel complex 4 using cyclopentadiene 2 2 as a ligand.
在镍促进的环化反应中,1,3-二烯可以用作配体,并影响反应过程。甲小号-顺式-1,3-二烯的构象是必要的协调,以金属,和最高的选择性(在的反应得到)1b中与氢化镍络合物4使用环戊二烯2 2作为配体。
