Elimination, Substitution, and Addition Reactions Resulting in Carbon–Carbon Bond FormationIn the presence of strong acid, formic acid decomposes to water and carbon monoxide. In the process, reactive intermediates form that are capable of direct carboxylation of carbonium ions. As many carbonium ions...
The method of choice for the reduction of keto groups to methylenes remains the Wolff-Kishner reaction. Originally, the hydrazone formation was carried out in a separate step, followed by decomposition with base under pressure. The Huang-Minion modification allows the reaction to be carried out ...

Addition reactions are reactions that add additional atoms to the original compound. This is in contrast to substitution reactions, where one compound is substituted for another, and it is the opposite reaction of elimination reactions, where atoms are removed from the original compound. Addition ...
2.6.1 Representative ?-Elimination Reactions 1. primary t-BuOK: favors elimination over substitution, as compared with less branced alkoxides. 53 2. The issues of regiochemistry and stereochemistry arise, even with a relatively simple reactant; substitution can compete with elimination in unhindered...
What are the major reactions in organic chemistry? There are six main types of reactions in organic chemistry. These reactions include addition reactions, elimination reactions, substitution reactions, rearrangement reactions, polymerization, and cracking. What is an example of an organic chemistry reactio...
Kinetic deuterium isotope effects show that the anionic bases induce the E2 elimination (kH/kD > 2), while the amines allow formation of a cyclohexenyl cation in chloroform to lead to E1 as well as SN1 reactions (kH/kD ≈ 1). Bases are much less effective in methanol, and methoxide ...
