Abstract:
A method for preparing an α-halo enal or enone from an unprotected propargyl alcohol and an electrophilic halogen source catalyzed by the combination of a gold catalyst complex and a metal co-catalyst complex is disclosed. The method can be further enhanced by addition of an additive that facilitates suppression of a des-halo derivative.
