Remarkable amine

The strong relation between stereochemistry and assembly results in the specific association characteristics of trans 4-tert-butyl-1-phenylcyclohexylamine when compared with the cis isomer. The cis isomer gives rise to a highly abundant [M4TFA3+H]+ ion (M=amine molecule, TFA=trifluoroacetic acid), as observed for other primary amines.

Boc

The reaction of di-tert-butyl dicarbonate or a chloroformate and sodium azide with an aromatic carboxylic acid produces the corresponding acyl azide. The acyl azide undergoes a Curtius rearrangement to form an isocyanate derivative which is trapped either by an alkoxide or by an amine to form the aromatic carbamate or urea.

Amine Reactions

The nitrosyl cation is electron deficient. Its nitrogen has only three pairs of electrons in the valence shell, so it is a very good electrophile, very susceptible to attack by a nucleophile. When the nucleophile is a secondary amine, the product (after loss of an H + from the amine nitrogen) is called an N

Physical Properties of Amines

Primary and secondary amines have hydrogen atoms bonded to an nitrogen atom and are therefore capable of hydrogen bonding (part (a) of Figure 15.6 Hydrogen Bonding), although not as strongly as alcohol molecules (which have hydrogen atoms bonded to an oxygen atom, which is more electronegative than nitrogen).

carbocations (or carbonium ions)

We are actually talking about energetic stability - secondary carbocations are lower down an energy ladder than primary ones. This means that it is going to take more energy to make a primary carbocation than a secondary one. If there is a choice between making a secondary ion or a primary one, it will be much easier to make the secondary one.

What are primary, secondary and tertiary carbons

We use the terms primary, secondary, and tertiary to refer to the substitution level that a given carbon has in a molecule. In other words, these terms are used to describe how many other carbons a given carbon is attached to. So to figure out the substitution level of any given carbon, follow these three easy steps: Step #1: Pick a carbon

Boc Protected Compounds

Chiral diamines are prepared from Boc-protected amino acid-derived secondary amides. Selective Boc protection of the secondary amine in the presence of the primary amine is done by condensing the primary amine with benzaldehyde, followed by Boc protection at the secondary amine and hydrolysis of the imine to give the free primary amine.

Synthesis and selection of hindered new amine absorbents

An unhindered amine forms a weakly bonded intermediate called carb amate that is fairly stable. Only half a mole of CO 2 is absorbed per mole of amine, as shown in the CO 2 absorption equation above. On application of heat, this carbamate dissociates to give back CO 2 and amine absorbent, as shown in the second equation above. Since the

What is a secondary butyl?

Jun 09, 2016A secondary carbon is one that has two substituents. A substituent is any atom or group of atoms that are attatched to the carbon instead of a hydrogen atom. So a secondary carbon has the form [math] RCH_2R' [/math]. The term butyl indicates a ramification of four carbon atoms attatched to another hydrocarbon chain (or group of atoms).
