Electrolysis at a platinum cathode of ethyl alk-2-ynoates in the presence of an excess of alkyl iodide in hexamethylphosphoramide or dimethylformamide solution containing tetra-n-butylammonium iodide gave the corresponding non-conjugated dialkylation products, ethyl 2,2-dialkylalk-3-ynoates, in good yield.
在过量烷基碘的存在下,在含有碘化四正丁基铵的六甲基磷酰胺或二甲基甲酰胺溶液中,在烷基碘的存在下,在烷基铂-2-阴极上电解得到相应的非共轭二烷基化产物2,2-二烷基烷基-3 -叶酸盐,产率高。
