Methoxymethylation of a variety of alcohols was performed using formaldehyde dimethyl acetal in the presence of N,N,N',Ν'-tetrabromobenzene-1,3-disulfonamide [TBBDA] and poly(N-bromo-N-ethyl-benzene-l,3-disulfonamide) [PBBS] as catalysts at room temperature and solvent-free conditions. The methoxymethyl ethers (MOM-ethers) were obtained with good to excellent yields.
在 N,N,N',N'-四溴苯-1,3-二磺酰胺 [TBBDA] 和聚 (N-溴-N-乙基-苯-1) 存在下使用甲醛二甲基缩醛对各种醇进行甲氧基甲基化,3-二磺酰胺) [PBBS] 在室温和无溶剂条件下作为催化剂。以良好至优异的产率获得甲氧基甲基醚(MOM-醚)。
