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.
Bistriflimide 催化的乙酸苄酯与三甲基(炔基)硅烷和三甲基(烷氧基)硅烷的偶联反应分别产生炔丙基芳烃和苄基烷基醚。酸有助于将反应性三甲基硅离子释放到介质中,这是最终的催化物质。过程的阳离子性质已记录在案。
