Zusammenfassung

Während die Kondensation von Dimedon mit Aldehyden ausschließlich zuMichaeladditionsprodukten (Molverhältnis 2:1) führt, erhält man aus dem Natriumsalz des Dimedons und Aldehyden die entsprechenden Äthylene (1:1-Produkte); diese sind starke organischeLewissäuren.

Abstract

Michael reaction-type condensations of aldehydes with dimedone generally lead to reaction products which are made up from 2 moles of aldehyde and 1 mole of dimedone. However, if the sodium salt of dimedone is used, reaction products corresponding to a molar ratio 1:1 are obtained. These substituted ethylenes are strong organicLewis acids.
