双羰基化合物的Wittig反应

THE WITTIG REACTIONS OF DICARBONYL COMPOUNDS

以二甲基亚砜钠和苯基锂为碱,对双羰基化合物的Wittig反应进行了初步的研究.对苯二甲醛的单Wittig产率为30～41%,而双Wittig产率则为12～15%;脂肪二醛的单Wittig产率为0,而双Wittig产率为12～15%;二酮的两种产率都为0.

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.
