首次以芳基三氮烯为新型亲电底物进行Stille偶联反应研究.反应在室温、氩气保护下进行.溶剂、两底物物质的量比、催化剂用量等影响收率的因素被优化,取得最佳的优化条件,获得较好的收率.芳基三氮烯通过助催化剂路易斯酸迁移到钯化合物,偶联反应由钯催化剂催化完成.产物纯化通过硅胶柱层析完成,结构被1H NMR,13C NMR确定.

关键词: 芳基三氮烯, 偶联反应, 三丁基苯基锡

The Stille cross-coupling reaction of aryltriazene as a novel electrophilic substrate has been realized for the first time. The reactions were performed at room temperature under an argon atmosphere. Solvents, molar ratio of aryltriazene/tributyl(phenyl)stannane, amount of catalyst were optimized and excellent yield was obtained. Aryltriazene via Lewis acid-assisted was transferred to palladium(II) compound. Cross-coupling reactions were catalyzed by palladium(II) compound. The products were purified via column chromatography on silica gel. Structures of all products were confirmed by 1H NMR and 13C NMR techniques.

Key words: aryltriazenes, cross-coupling reaction, tributyl(phenyl)stannane
