Insertion reaction refers to a type of chemical reaction where an atom or a group of atoms is inserted into an existing molecule. This insertion can occur in various ways, depending on the nature of the reactants and the reaction mechanism. One common type of insertion reaction involves the addition of a carbene or nitrene species into a bond, such as a carbon-carbon or carbon-hydrogen bond. These reactions are often facilitated by transition metal catalysts.

Another significant category of insertion reactions is seen in organic chemistry, particularly in the context of addition reactions across double or triple bonds. For instance, the addition of halogens or hydrogen halides to alkenes and alkynes are examples of insertion processes, where the added atoms are inserted into the pi system of the unsaturated bond. Polymerization reactions can also be viewed as a series of insertion events, where monomer units are sequentially inserted into a growing polymer chain.

Insertion reactions are crucial in many synthetic pathways, enabling the construction of complex molecules from simpler precursors. They are widely employed in organic synthesis for the formation of new carbon-carbon and carbon-heteroatom bonds. The regioselectivity and stereoselectivity of insertion reactions can often be controlled by the choice of catalyst and reaction conditions, making them valuable tools for chemists. Understanding the mechanisms of these reactions is essential for predicting product formation and designing efficient synthetic strategies.
