Reactivity of amine in Urea
« on: September 06, 2012, 03:01:36 PM »
Hi,

I was wondering what is the reactivity of primary amines in urea is towards electrophiles. I know it reacts well with aldehydes (urea formaldehyde resin for example). How about epoxy functional groups? Thanks

best

The NH2 groups of urea are reasonable reactive towards electrophiles.
Urea/formaldehyde is a polymer and when you talk about epoxides I suppose you mean polymerisation? If so then you will get polymerisation.
Urea should react with epoxides under normal conditions as well.

Urea reacts with epoxy compounds and can form chelating complexes.
