Lewis acid catalyzed propargylation of arenes with O-propargyl trichloroacetimidates: synthesis of 1,3-diarylpropynes.
The BF3.OEt2-catalyzed Friedel-Crafts propargylation of aromatic compounds with O-propargyl trichloroacetimidates is highly efficient and affords 1,3-diarylpropyne derivatives in good yields.
