摘要

A Brønsted acid-catalyzed hydroamination of unactivated olefins has been developed, enabling the efficient Markovnikov addition of nitrogen heterocycles to olefins. This reaction utilizes a catalytic amount of trifluoroacetic acid (TFA) to produce a diverse array of N-alkyl nitrogen heterocycles. The method is highly scalable, allowing for multigram synthesis, and a novel proton transfer species implicated in olefin activation has been identified.
