Summary
N-demethylation is the primary reaction pathway for tertiary N-methyl amines, with other alkyl-nitrogen bond cleavage pathways being less likely. Structure-reactivity maps effectively predict these outcomes.
Area of Science:
- Organic Chemistry
- Chemical Reactivity
Background:
- Tertiary amines undergo various N-dealkylation reactions.
- Understanding the relative rates of these reactions is crucial for predicting chemical behavior.
Purpose of the Study:
- To investigate the predominant reaction pathways for tertiary N-methyl amines.
- To establish structure-reactivity relationships for N-dealkylation reactions.
Main Methods:
- Analysis of alkyl-nitrogen bond cleavage in a range of tertiary N-methyl amines.
- Utilizing structure-reactivity maps to visualize and interpret reaction outcomes.
Main Results:
- N-demethylation was consistently observed alongside alkyl-nitrogen bond cleavage.
- Alkyl-nitrogen bond cleavage within rings or involving ring structures was less likely than N-demethylation.
- Structure-reactivity maps revealed clear relationships for N-debenzylation, N-dethiophenation, and N-dedimethylaminoethylation.
Conclusions:
- N-demethylation is the favored reaction for tertiary N-methyl amines.
- Structure-reactivity maps are valuable tools for predicting the influence of structural environments on N-dealkylation pathways.

01:46Oxidative Cleavage of Alkenes: Ozonolysis
In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

02:01Alkynes to Carboxylic Acids: Oxidative Cleavage
Alkynes undergo oxidative cleavage in the presence of oxidizing reagents like potassium permanganate and ozone. The triple bond — one σ bond and two π bonds — is completely cleaved, and the alkyne is oxidized to carboxylic acids. When warm and basic aqueous potassium permanganate is used as an oxidizing agent, alkynes are first converted to carboxylate salts via an unstable α-diketone intermediate. Further, a mild acid treatment protonates the carboxylate anions generating free carboxylic acid...
01:13¹H NMR: Complex Splitting
A proton M that is coupled to a proton X results in doublet signals for M. However, NMR-active nuclei can be simultaneously coupled to more than one nonequivalent nucleus. When M is coupled to a second proton A, such as in styrene oxide, each peak in the doublet is split into another doublet.
Splitting diagrams or splitting tree diagrams are routinely used to depict such complex couplings. While drawing splitting diagrams, the splitting with the larger coupling constant is usually applied first.

01:20Mass Spectrometry: Molecular Fragmentation Overview
The ionization of a molecule into a molecular ion inside the mass spectrometer causes instability in the molecule's structure due to the loss of an electron. This eventually leads to the fragmentation or breaking of some bonds in the molecule. The fragmentation occurs predominantly at specific bonds to yield relatively stable fragments.
One type of fragmentation pattern is the cleavage of a single bond in the molecular ion. The cleavage leads to a radical and a cation. The cleavage can occur at...

01:29Mass Spectrometry: Branched Alkane Fragmentation
This lesson delves into the mass spectrometry of branched alkane fragmentation. Branched alkanes possess secondary or tertiary carbon atoms, which generate relatively stable carbocations if the cleavage occurs at the branching point. The high stability of carbocations drives the instant fragmentation of branched alkanes. Accordingly, the branched alkane's molecular ion peak is very weak or invisible in the mass spectra, especially in comparison to a linear alkane.
01:01Mass Spectrometry: Carboxylic Acid, Ester, and Amide Fragmentation
The fragmentation patterns observed for compounds such as carboxylic acids, esters, and amides in the mass spectra include ⍺-cleavage and McLafferty rearrangement. Fragmentation by ⍺-cleavage preferentially occurs at the carbon-carbon bond at the ⍺-position next to the carboxylic group to generate a neutral radical and a cation. Long chain compounds with hydrogen at their γ-carbon undergo McLafferty rearrangement to give a radical cation and a neutral alkene.
For example, the fragmentation of...
