The influence of ligands on the result of a metal‐catalyzed reaction has been studied for the formation of dimers and trimers from butadiene with Ni 0 /PR 3 . Multilinear regression analysis showed the oligomer distribution to be largely dependent upon “steric” factors. Large and small apical angles favor cyclotri‐merization, and increasing donor character has the same effect. (Su = substrate = butadiene, m = 0 or 1.)
