A general and efficient FeCl3-catalyzed substitution reaction of
propargylic alcohols with carbon- and heteroatom-centered nucleophiles such
as allyl trimethylsilane, alcohols, aromatic compounds, thiols, and amides,
forms new C-C, C-O, C-S and C-N bonds.

The reaction of alkoxides with boron trichloride results in the generation
of cations that can be allylated in subsequent transformations. The absence
of Brønsted acids can make a significant difference in such syntheses.
