2′-dihydroxy-1,1′-binaphthyl) under mild basic conditions and its methyl and triisopropylsilyl ethers has been investigated in neat and aqueous acetonitrile through product distribution analysis and laser flash photolysis. Arylation and alkylation have been successfully achieved in the presence of allyltrimethylsilane, ethyl vinyl ether, pyrrole, pyridine, thiophene, benzene, and indole. Such a photoreactivity
通过产物分布分析,研究了6,6'-二溴-BINOL(BINOL = 2,2'-二羟基-1,1'-联萘)在温和的碱性条件下及其甲基和三异丙基甲硅烷基醚在纯乙腈和水性乙腈中的光化学性质。和激光闪光光解。在烯丙基三甲基硅烷,乙基乙烯基醚,吡咯,吡啶,噻吩,苯和吲哚的存在下已成功实现了丙烯酸化和烷基化。这种光反应性提供了针对单取代和双取代的6-芳基/烷基BINOL的无金属和保护基的合成方案,因为在光活化过程中保持了BINOL手性。
