A simple Re2O7-catalyzed direct dehydrative coupling between π-activated alcohols with electron-deficient amines has been achieved under mild and open flask conditions. The protocol alows the conversion of allylic, benzylic, and propargylic alcohols. The mechanistic proof for the SN1-type process has also been provided.
