Imines naturally tautomerize to form: (A) oximes. (B)...

Key Concepts

Imines

Imines are compounds that feature a carbon-nitrogen double bond created typically by the condensation of carbonyl compounds with primary amines. They play an important role in organic synthesis as intermediates that can undergo further chemical transformations.

Tautomerization

Tautomerization is a process in which a chemical compound undergoes a rearrangement of atoms, usually involving the migration of a proton and the shifting of a double bond. This process results in the formation of constitutional isomers, known as tautomers, which have different chemical properties.

Enamines

Enamines are a class of compounds that result from the tautomerization of imines. They feature an amine group attached adjacent to a carbon-carbon double bond, which makes them useful as nucleophilic intermediates in various organic reactions.

Transcript

00:01 Okay, this problem is asking us which of these molecules between all four of these is my immune going to naturally tatamorize in two.

00:07 So let's go ahead and define a couple terms here.

00:09 First off, tatomerization or tatmarization is essentially isomerization, right? because whatever we have right here, in this case we have an amine, the tatamer, the tautomer, is going to be in equilibrium.

00:22 It exists in equilibrium with my amine.

00:25 So in order to exist in equilibrium, that means that we're going to have basically the same atoms as we do in this immune, but just in a different order, right? we're going to have different connections, basically another isomer, which is going to be called the totemir in this case.

00:39 So we're looking among all these molecules, which one has the same atoms just in different connections.

00:44 So over here we have an oxyme.

00:46 Does this have the same number of atoms, the same type of atoms? the answer is no, right? because we have an oxygen here that is simply not a component of my amine, so this is not going to be an option.

00:57 Next step, we have a hydrozone.

00:59 Is this considered to be the same atoms as we do in my amine? the answer is no, right? because we have another nitrogen, right? we have the extra nitrogen that is not an option.

01:09 Next up, we have this semicarposone.

01:11 This is obviously not the right answer because this one has way too many nitrogens, right? we have one too many...
