In organic chemistry, an addition reaction is, in simplest terms, an organic reaction where two or more molecules combine to form a larger one (the adduct).. In organic chemistry, ozonolysis is an organic reaction where the unsaturated bonds of alkenes (C=C), alkynes (CC), or azo compounds (N=N) are cleaved with ozone (O 3).Alkenes and alkynes form organic compounds in which the multiple carboncarbon bond has been replaced by a carbonyl (C=O) group while azo compounds form nitrosamines (NN=O). This reaction is widely used for the synthesis of various phosphonates, phosphinates, and phosphine oxides.Several reviews have been published. It is believed to occur via a single, cyclic transition state, with no intermediates generated during the course of the reaction.
Aldol reaction Olefin metathesis is an organic reaction that entails the redistribution of fragments of alkenes (olefins) by the scission and regeneration of carbon-carbon double bonds. The mechanism begins by the addition of the Grignard reagent (2) onto the nitroarene (1) to form intermediate 3.Intermediate 3 spontaneously decomposes to form a nitrosoarene (4) and a magnesium salt (5).
