results show that alcohols and alkynes protected by these groups are phase-selectively soluble in hydrocarbon solvents. In a thermomorphic cyclohexane/DMF system, >96% of the silylated alcohols are in the cyclohexane phase, allowing these compounds to be purified by a simple liquid/liquid extraction. Applications of these silylating agents in a Grignard synthesis and Sonogashira reaction are described
描述了使用庚烷相选择性溶解的十八烷基二甲基甲硅烷基基团以促进分离和甲硅烷基试剂再生的方法。这些结果表明,由这些基团保护的醇和炔烃在烃溶剂中是相选择地可溶的。在热定型环己烷/ DMF系统中,> 96%的甲硅烷基化醇都在环己烷相中,从而可以通过简单的液/液萃取来纯化这些化合物。描述了这些甲硅烷基化剂在格利雅(Grignard)合成和Sonogashira反应中的应用。
