Electrolysis of aromatic aldehydes and malononitrile in alcohols in an undivided cell in the presence of a NaBr-NaOAc mediatory system stereoselectively gave bicyclic compounds containing the cyclopropane and pyrroline fragments in 60 to 70% yields. In the bicyclic products, the benzene and pyrroline rings are on different sides of the cyclopropane ring.__________Published in Russian in Izvestiya Akademii Nauk.

Electrolysis of dialkyl ketones in MeOH in the presence of the NaI—NaOH mediator system placed in an undivided cell involves a process analogous to the Favorsky rearrangement of ,-dihalodialkyl ketones giving rise to methyl esters of ,-unsaturated carboxylic acids in 70—75% substance yields and 60—70% current yields. 相似文献

The new reaction was found: the direct formation of cyclopropanes from activated olefins and C-H acids. The action of free halogen or active halogen containing compounds on the equal amounts of benzylidenemalononitriles and malononitrile in basic alcohol solutions results in the formation of 3-aryl-1,1,2,2-tetracyanocyclopropanes in 65-95% yields. Thus, the new simple and efficient way to 3-aryl substituted tetracyanocyclopropanes was found directly from such simple and reasonable starting compounds as benzylidenemalononitriles and malononitrile. 相似文献
