developed for the decarboxylative allylation of ortho-nitrobenzoic esters in an intramolecular fashion. In contrast to the typical sp2–sp3 cross-coupling approach which requires air and moisture sensitive preformed organometallic reagents, we provide an alternative route to the synthesis of ortho-allyl nitroarenes from the corresponding ortho-nitrobenzoic acid derivatives. The reaction proceeds through
已经开发了一种Pd / Ag双金属体系,用于以分子内方式对邻硝基苯甲酸酯进行脱羧烯丙基化。与典型的sp 2 –sp 3交叉偶联方法需要空气和水分敏感的预制有机金属试剂相反,我们提供了从相应的邻硝基硝基苯甲酸衍生物合成邻烯丙基硝基芳烃的另一种途径。该反应通过机械上独特的脱羧金属化途径进行。钯和银的协同反应性对于反应结果至关重要。
