The addition of hydrogen and an amino group (NR 2) using reagents other than the amine HNR 2 is known as a "formal hydroamination" reaction. Although the advantages of atom economy and/or ready available of the nitrogen source are diminished as a result, the greater thermodynamic driving force, as well as ability to tune the aminating reagent ...
The following outline is provided as an overview of and topical guide to organic chemistry: Organic chemistry is the scientific study of the structure, properties, composition, reactions , and preparation (by synthesis or by other means) of carbon -based compounds, hydrocarbons , and their derivatives.

Most often, each step in a synthesis is a separate reaction taking place to modify the starting materials. For more complex molecules, a convergent synthetic approach may be better suited. This type of reaction scheme involves the individual preparations of several key intermediates, which are then combined to form the desired product. [4]
Radical disproportionation encompasses a group of reactions in organic chemistry in which two radicals react to form two different non-radical products. Radicals in chemistry are defined as reactive atoms or molecules that contain an unpaired electron or electrons in an open shell. The unpaired electrons can cause radicals to be unstable and ...
The reaction mechanism of the Stevens rearrangement is one of the most controversial reaction mechanisms in organic chemistry. [4] Key in the reaction mechanism [5] [6] for the Stevens rearrangement (explained for the nitrogen reaction) is the formation of an ylide after deprotonation of the ammonium salt by a strong base.

However, several reactions have been identified that fit the concept better than others: [clarification needed] [3+2] cycloadditions, such as the Huisgen 1,3-dipolar cycloaddition, in particular the Cu(I)-catalyzed stepwise variant, [6] are often referred to simply as Click reactions; Thiol-ene reaction [7] [8]
