What is another word for cycloaddition?
Pronunciation: [sˌa͡ɪklə͡ʊdˈɪʃən] (IPA) 
Cycloaddition is a commonly used term in chemistry, referring to a reaction in which two unsaturated molecules react to form a cyclic compound. However, there are several different types of cycloaddition reactions, each with their own unique characteristics and conditions. For example, [2+2] cycloaddition involves the addition of two unsaturated molecules with double bonds, while [4+2] cycloaddition involves four unsaturated molecules with double bonds. Other synonyms for cycloaddition include Diels-Alder reaction, Hecke reaction, Pauson-Khand reaction, and Diels-Alder-like reaction. With the use of different reagents and conditions, each of these reactions can be selectively and efficiently carried out, making cycloaddition a powerful tool in the synthesis of complex organic molecules.
