Can an amine have a double bond

WebH bonds. Tertiary amines have no H-bond donor, since they have three alkyl groups on the nitrogen. Tertiary amines can not H-bond to each other, lowering their boiling points, but small 3 o amines are still soluble in water, since they do have an H-bond acceptor (N:). Reacting amines with strong acids leads to the protonation of the amine. WebThe maleimide carbon–carbon double bond is strongly electrophilic and can react with nucleophilic reagents such as amines and thiols as shown in Scheme 15. 70 The addition with thiols has to be carried out in protic solvents in order to avoid the side reactions of intermediate anionic maleimido species with maleimide, resulting in cross-linking.

WebWe can see all of this put together and we can also see that, while the double-bonded O is neutral, having six electrons assigned to it, the three single bonded O atoms have seven electrons assigned and therefore carry a -1 charge. There is no reason, however, why we should select the top O atom as the one to have a double-bond. WebThe double bond of the carbonyl group is therefore shorter and stronger, and exhibits a larger stretching frequency. 3. Electron donating substituents on the carbonyl group stabilize the ionic resonance contributor, and increase the single bond character of the C=O bond.
