Synthesis of dienic scaffolds by Fe-mediated coupling between Grignardreagents and dienyl bromides is reported. This methodology involves the use of magnesium alkoxides as additives, and can be applied to targets of industrial interest, such as insect pheromones. Mechanistic studies suggest that the active species is an organoiron(II) complex, showing that no reduction of the precursor to low oxidation
报道了通过格氏试剂和二烯基溴之间的 Fe 介导的偶联合成二烯支架。该方法涉及使用烷氧基镁作为添加剂,并且可以应用于具有工业意义的目标,例如昆虫信息素。机理研究表明,活性物质是一种有机铁 (II) 复合物,表明不需要将前体还原为低氧化态。
