The Hofmann Elimination

The Hofmann Elimination is an elimination reaction of alkylammonium salts that forms C-C double bonds [pi bonds]. [note] It proceeds through a concerted E2 mechanism. In contrast with

The Cope Elimination

The “Cope Elimination” is a reaction where an amine is oxidized to an intermediate called an “N-oxide”, which, when heated, acts as the base in

Introduction to Rearrangement Reactions

The previous four posts on acid-base, substitution, addition, and elimination covered the 4 main reactions in organic chemistry I. Now it’s time to go beyond

Elimination Reactions of Alcohols

Here’s a summary of what we talk about in today’s post. Hydrohalic acids (HX) plus alcohols give substitution products… We just saw that treating an

Elimination of Alcohols To Alkenes With POCl3

Here’s what we talk about today: more eliminations of alcohols! Note that this reagent isn’t covered in all courses, but I’ll include it here for completeness’

Addition Reactions: Elimination’s Opposite

In previous series, we’ve discussed acid-base reactions, nucleophilic substitution reactions, and elimination reactions. These represent three of the four most important reaction types in a

Deciding SN1/SN2/E1/E2 (1) – The Substrate

Having gone through the SN1, the SN2, the E1, and the E2 reactions in turn, we can now say the following: Both substitution reactions and elimination

Guest Post on SN1/SN2/E1/E2 (4): The Electrophile

For the previous posts in Adam’s series on the SN1/SN2/E1/E2, see Part 1 Part 2 Part 3. – James Three And A Half Steps To

Guest Post on SN1/SN2/E1/E2 (2): Three And A Half Steps To Any Substitution Or Elimination Reaction

The second in a series of guest posts on SN1/SN2/E1/E2 by Chemistry Blog author and “instructor of organic chemistry at a small Midwestern liberal arts

Alkynes Via Elimination Reactions

We’ve gone through elimination reactions before – treatment of alkyl halides with base gives alkenes. Some time ago we discussed elimination reactions here. Elimination reactions
