Cyclic ketone enamines follow a reactivity trend where the five membered ring is the most reactive due to its maximally planar conformation at the nitrogen, following the trend 5>8>6>7 (the seven membered ring being the least reactive).
Which is more stable imine or enamine?
An imine is a functional group or chemical compound containing a carbon–nitrogen double bond. ... Imines are more stable than enamines and an enamine will form only if the formation of the imine is not possible.
Why are enamines better nucleophiles than enols?
The electron density at the α carbon atom in enamines is greater than that in enols because nitrogen is less electronegative than oxygen and releases an electron pair more readily. As a result, enamines are more nucleophilic than enols, and they are useful intermediates in alkylation reactions.
