In this study, a one-pot two-step Pd-catalyzed reductive eliminate between acetyl naphthalene derivatives, tosylhydrazide, and aryl halide, affording substituted 1(or 2)-(1-phenylvinyl)naphthalene in moderate-to-excellent yields, was reported. Notably, solvent played a crucial role in the coupling of 1-acetyl naphthalene derivatives (toluene) or 2-acetyl naphthalene derivatives (1, 4-dioxane) as starting
在这项研究中,一锅两步Pd催化的乙酰萘衍生物,甲苯磺酰肼和芳基卤化物之间的还原消除,以中等至优异的产率提供了取代的1(或2)-(1-苯基乙烯基)萘。报告。值得注意的是,溶剂在作为起始原料的1-乙酰基萘衍生物(甲苯)或2-乙酰基萘衍生物(1,4-二恶烷)的偶联中起关键作用。同时,该一锅偶联反应的范围扩展到了1(或2)-萘醛底物。重要的是,该催化体系可用于具有良好官能团耐受性的多种底物上。该方案对于烯烃-取代基羟基化合物的合成也可能特别有用。
