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.
本发明提供了化合物,可用作安全替代有机锡试剂,用于偶联反应中的氧甲基化反应,例如烷氧甲基化或羟甲基化,使用钯催化剂,且可在生产过程中省去硅胶色谱纯化步骤,并适用于大规模生产;同时,这些化合物也适用于传统技术无法进行偶联反应或反应活性较低的芳环底物的氧甲基化反应。
