A new method to obtain activated manganese metal, especially attractive for large scale preparative organic chemistry, is described. The key point is the use of 2-phenylpyridine as electron carrier to reduce manganese chloride by lithium. The active manganese thus obtained was used to prepare various organomanganese reagents from organic halides. The reactivity of these reagents has been studied (acylation
描述了一种获得活化的锰金属的新方法,该方法对大规模制备有机化学特别有吸引力。关键是使用2-苯基吡啶作为电子载体,通过锂还原氯化锰。如此获得的活性锰用于由有机卤化物制备各种有机锰试剂。已经研究了这些试剂的反应性(酰化,1,2-或1,4-加成,烷基化和烯基化)。
