摘 要:研究了1-三甲基硅基甲基-3-烷基咪唑類(lèi)離子液體和1-正丙基-3-烷基咪唑類(lèi)離子液體分別作為溶劑在鄰胺基烷基苯酚合成中的應用,并合成了九種2-(1-(取代苯胺)乙基)苯酚目標產(chǎn)物。結果表明,兩類(lèi)離子液體做溶劑與無(wú)水乙醇做溶劑相比均能提高目標產(chǎn)物的收率,其中含硅離子液體的溶劑效應優(yōu)于不含硅離子液體;并推測了反應機理。含硅離子液體在反應中表現出一定的催化活性。

Abstract:The application of 1-trimethylsilylmethyl-3-alkylimidazolium ionic liquids as solvent in the synthesis of 2-(1-(substituted aniline) ethyl) phenol was evaluateded compared to 1-n-propyl-3-alkylimidazolium ionic liquids. The results showed that the yields of the target products were all improved, and the solvent effect of the silicon-containing ionic liquid was better than that of non-silicon-containing ionic liquid; and the reaction mechanism was presented. In addition, silicon-containing ionic liquid also performanced as a role of catalysis in the reaction.
Key words:silicon-containing ionic liquid; synthesis; reaction mechanism
