In organic chemistry, an addition reaction is an organic reaction in which two or more molecules combine to form a larger molecule called the adduct. [ 1 ] [ 2 ] An addition reaction is limited to chemical compounds that have multiple bonds .
The Woodward cis-hydroxylation (also known as the Woodward reaction) is the chemical reaction of alkenes with iodine and silver acetate in wet acetic acid to form cis-diols. [1] [2] (conversion of olefin into cis-diol) The reaction is named after its discoverer, Robert Burns Woodward. The Woodward cis-hydroxylation
Hydroacylation is a type of organic reaction in which an electron-rich [1] unsaturated hydrocarbon inserts into a formyl C-H bond. With alkenes, the product is a ketone: RCHO + CH 2 =CHR' → RC(O)CH 2 CH 2 R' With an alkyne instead, the reaction produces an α,β-unsaturated ketone. [2] The reaction requires a metal catalyst or a radical ...
In organic chemistry, syn-and anti-addition are different ways in which substituent molecules can be added to an alkene (R 2 C=CR 2) or alkyne (RC≡CR).The concepts of syn and anti addition are used to characterize the different reactions of organic chemistry by reflecting the stereochemistry of the products in a reaction.
The most important industrial application is the nickel-catalyzed synthesis of adiponitrile (NC−(CH 2) 4 −CN) synthesis from buta-1,3-diene (CH 2 =CH−CH=CH 2).Adiponitrile is a precursor to hexamethylenediamine (H 2 N−(CH 2) 6 −NH 2), which is used for the production of certain kinds of Nylon.
Reactions of conjugated double-bond systems can be synthesized into cycloalkenes through electrocyclic reactions. [13] Addition of heat or photolysis causes a reversible reaction that causes one pi bond to become a sigma bond, which closes the ring and creates a cycloalkene.

In organic chemistry, free-radical addition is an addition reaction which involves free radicals. These reactions can happen due to the free radicals having an unpaired electron in their valence shell, making them highly reactive. [1] Radical additions are known for a variety of unsaturated substrates, both olefinic or aromatic and with or ...
