| Abstract: | The Wittig reactions of dicarbonyl compounds were researched using sodium dimethyl sulfoxide or phenyllithium as base. The single Wittig yields of terephthalaldehyde were 30-41%, but the double Wittig yields were 12-15%. The single Wittig yields of the aliphatic dialdehydes were O, while the double Wittig yields were 12-15%. The single and double Wittig yields of diketones were O. |
