ABSTRACT

The presence of halide ions in the anolyte may efficiently help the oxidative addition of the solvent to an unsaturated compound; the addition may be followed by a bond cleavage [164]. The conversion of furan into either 2,5-dimethoxy-2,5-dihydrofuran [165,166] or 2,5-diacetoxy-2,5-dhydrofuran [167] has been shown to be possible in methanol or an acetic acid-acetonitrile mixture, respectively (Scheme 24).
