Bistriflimide-catalyzed coupling reactions of benzylacetates with both trimethyl(alkynyl)silanes and trimethyl(alkoxy)silanes lead to propargyl arenes and benzyl alkyl ethers, respectively. The acid assists the release of the reactive trimethylsilylium ion into the media, which is the ultimate catalytic species. The cationic nature of the processes is documented.
