the deprotection of bulky (trialkylsilyl)acetylenes. Treatment of 1-(triisopropylsilyl)acetylenes with silver fluoride, followed by hydrolysis of the intermediate silver acetylide with organic or inorganic acids, produces terminal acetylenes in good to excellent yields. The reactions are chemoselective and various functional groups are tolerated. desilylation - trialkylsilyl - silver fluoride - chemoselectivity
开发了一种有效且温和的方法来对大体积的(三烷基甲硅烷基)乙炔进行脱保护。用氟化银处理1-(三异丙基甲硅烷基)乙炔,然后用有机酸或无机酸水解中间体乙炔化银,以良好或优异的产率产生末端乙炔。反应是化学选择性的,并且可以容忍各种官能团。 脱甲硅烷基-三烷基甲硅烷基-氟化银-化学选择性-炔烃
