Generation of cations from alkoxides: allylation of propargyl alcohols.
The reaction of alkoxides with boron trichloride results in the generation of cations in the absence of Brønsted acids. The absence of a Brønsted acid can make a difference in subsequent transformations such as allylation reactions.
