The present invention provides compounds which are useful as safe substitutes for the organotin reagent used in coupling reaction for the oxymethylation of aromatic rings, such as alkoxymethylation or hydroxymethylation, with a palladium catalyst and which can dispense with chromatographic purification with silica gel in the production and are suitable for mass production; and compounds applicable even to the oxymethylation of aromatic ring substrates which do not permit coupling reaction by conventional technique or have low reactivity.
本发明提供了一些化合物,可用作在
钯催化下进行含
氧甲基化反应(如烷
氧甲基化或羟基
甲基化)的偶联反应中,
有机锡试剂的安全替代品。这些化合物可在生产中省去
硅胶色谱纯化步骤,并适用于大规模生产;并且这些化合物适用于那些传统技术无法进行偶联反应或反应活性较低的芳环基底物的含
氧甲基化反应。
