elaborate. The homologation of aldehydes to alkynes can also be extended to a single-step process by adding the aldehyde directly to the reaction mixture prior to isolation of the reagent. The homologation process using dimethyl (diazomethyl)phosphonate was shown to proceed also in nonprotic solvents with mild bases, emphasizing the importance of a facile access to the reagent. The oxidation of alcohols
摘要 (重氮甲基)
膦酸二甲酯的合成是一种用于
醛类同系化为
炔烃的有用试剂,被描述为一锅法,包括
叠氮化物转移剂的生成、重氮转移至
(2-氧代丙基)膦酸二甲酯和
甲醇分解,然后是一个简单的提取方案。先前描述的这种散装产品的合成要复杂得多。通过在分离试剂之前将醛直接添加到反应混合物中,醛与炔的同系化也可以扩展为单步过程。使用(重氮甲基)
膦酸二甲酯的同系化过程也被证明在弱碱的非质子溶剂中也能进行,这强调了易于获得试剂的重要性。
