RESUMO
Under nickel catalysis, in the presence of 3-hexyne, the aldimines of aromatic amines react with Ph2Zn and one molecule of butadiene to provide 1 exclusively, while the aldimines of aliphatic amines react with Ph2Zn and two molecules of butadiene to provide 2 exclusively, where 3-hexyne serves as a spectator ligand controlling the selective formation of 1 and 2.

RESUMO
A nickel(0) species catalyzes the five-component connection reaction of dimethylzinc, alkynes, 1,3-butadiene, aldehydes, and amines, furnishing either 1 or 2 selectively in good yields depending on the kinds of amines, aromatic or aliphatic amines, respectively.
