A new method for the synthesis of propargylated aromaticcompounds is developed. The reaction was carried out at room temperature in the presence of a catalytic amount of FeCl3 in acetonitrile, high product yields were obtained with excellent regioselectivity and the reaction proceeded smoothly without exclusion of moisture or air.

A general and efficient BiCl3-catalyzed substitution reaction of propargylic alcohols with carbon and heteroatom-centered nucleophiles such as allyl trimethylsilane, alcohols, aromatic compounds, thiols and amides, leading to the construction of C–C, C–O, C–S and C–N bonds, has been developed.
