The anodic fluorination of dimethyoxyethane (DME), and diethylene glycol dimethyl ether in acetonitrile containing a fluoride salt as a supporting electrolyte and a fluoride ion source using an undivided cell provided the corresponding monofluoromethyl ethers as a main product in good yields. On the other hand, anodic fluorination of crown ethers resulted in carbon–carbon bond cleavage which led to
使用不分开的电池,在含有氟化物盐作为支持电解质和氟化物离子源的乙腈中,对二甲氧基乙烷(DME)和二甘醇二甲醚进行阳极氟化,以高收率提供了相应的一氟甲基醚作为主要产物。另一方面,冠醚的阳极氟化作用导致碳-碳键裂解,从而导致高产率地选择性生产α,ω-二氟产物。当将Et 3 N·5HF用作支持电解质时,发现碳阳极和铂阳极对于电解氟化是有效的。
