Brønsted base-catalyzed imino-ene-type allylation reactions of simple alkenes as unactivated allyl compounds.

Catalytic imino-ene-type allylation reactions of unactivated allyl compounds were achieved. In the presence of a catalytic amount of a strongly basic KO t Bu-LiTMP or NaO t Bu-LiTMP mixed system, the desired reactions proceeded smoothly at low temperature. Notably, a gaseous alkene, propylene, could also be used in this reaction system.
