Аннотация
Abstract Direct Grignard type addition of terminal alkynes to in situ generated imines, from aldehydes and amines, occurs under microwave irradiation using CuBr alone in a one‐pot operation. This solventless approach provides ready access to propargylamines and is applicable both to aromatic and aliphatic aldehydes.
