Reactions of morpholine, pyrrolidine, di-n-propylamine, aniline, and n-butylamine with allene in the presence of a nickel salt and di-isopropoxyphenylphosphine have been studied. Mixtures of 1 : 1, two 1 : 2, and two 1 : 3 amine-allene adducts were formed, and with the exception of n-butylamine, the 1 : 3 adducts constituted >50% of the product amines. An essentially analogous reaction occurred with
