Two‐Phase Catalysis: A Strategy for Avoiding Consecutive Reactions as Exemplified in the Telomerization of Butadiene and Ammonia

The industrially interesting primary octadienylamines 1 and 2 can be synthesized selectively for the first time from 1,3-butadiene and ammonia. The use of an aqueous catalyst phase together with an organic solvent as a second phase are the key to the success of this process. Consecutive reactions of the primary amines 1 and 2, which are more nucleophilic than ammonia, can thus be avoided.
