Radical Substitution of Hydrogen by Anodically Generated Radicals

CH3C1 cf4, ccif3, chf3, chcif2, ch2f2, ch2cif, 179)  [Pg.61]

Malonic, succinic, maleic diesters Perfluorinated dicarboxylic acids (10-15 m) I 0 j) [Pg.61]

The supporting electrolyte is anodically oxidized to radicals, which abstract ohydrogen from the ether to form alkoxymethyl radicals that are subsequently oxidized to cations. An analogous route leads to alkenyl derivatives. [Pg.62]

A radical substitution path is assumed for the alkoxylation or acetoxylation of the methyl group in N,N-dimethylbenzamide, -acetamide or -formamide to the corresponding N-alkoxy- or N-acetoxymethyl derivatives 193-. An alternative path via radical cations has been proposed for the acyloxylation of amides on the basis of polarographic measurements and controlled potential electrolysis (Eq. (93) )48  [Pg.62]

Anodic methoxylation of cyclohexyl isocyanide yields a mixture of six products whose formation is thought to be initiated by methoxy radicals 194). Cholesteryl acetate dibromide has been specifically hydroxylated at C25 in 85 to 93% yield at a lead dioxide anode 19 s. Silyl ethers have been prepared in 60 to 95 % yield by electrolysis of trialkylsilanes at a platinum electrode in ROH- Me4NI, [Pg.62]
