Abstract
Terphenyl derivatives 3 and 4 having OTBS groups have been synthesized via a Suzuki-Miyura coupling reaction. These compounds undergo unprecedented irreversible cyclization to symmetrically/unsymmetrically substituted triphenylenes while carrying out the deprotection of OTBS groups using tetrabutylammonium fluoride. Terphenyl 3 also serves as a new chemodosimeter for fluoride ions.
摘要
具有 OTBS 基团的三联苯衍生物 3 和 4 已通过铃木-宫浦偶联反应合成。这些化合物在使用四丁基氟化铵脱除 OTBS 基团的同时，经历了前所未有的不可逆环化，生成对称/不对称取代的三联苯。三联苯 3 还可用作氟离子的新型化学计量型传感器。
