An addition reaction is the reverse of an elimination reaction, in which one molecule divides into two or more molecules. For instance, the hydration of an alkene to an alcohol is reversed by dehydration. There are two main types of polar addition reactions: electrophilic addition and nucleophilic addition.
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.
These side reactions can often be minimized by a judicious choice of reaction conditions. Dissolved oxygen is avoided since it is photoreactive. A variety of solvents can be used. Acetone is a useful solvent, because it can serve as a triplet sensitizer. Alkane-based solvents are selected to be free of alkenes. Excitation wavelength is important.
The Kharasch addition is an organic reaction and a metal-catalysed free radical addition of CXCl 3 compounds (X = Cl, Br, H) to alkenes. [1] The reaction is used to append trichloromethyl or dichloromethyl groups to terminal alkenes. The method has attracted considerable interest, [2] but it is of limited value because of narrow substrate scope ...
Adding the hydrogen ion to one carbon atom in the alkene creates a positive charge on the other carbon, forming a carbocation intermediate. The more substituted the carbocation, the more stable it is, due to induction and hyperconjugation. The major product of the addition reaction will be the one formed from the more stable intermediate.
The Prins reaction is an organic reaction consisting of an electrophilic addition of an aldehyde or ketone to an alkene or alkyne followed by capture of a nucleophile or elimination of an H + ion. [ 1 ] [ 2 ] [ 3 ] The outcome of the reaction depends on reaction conditions.
In organic chemistry, the thiol-yne reaction (also known as alkyne hydrothiolation) is an organic reaction between a thiol (−SH) and an alkyne (−C≡CH). The reaction product is an alkenyl sulfide (−CH=CH−S−). [1] [2] The reaction was first reported in 1949 with thioacetic acid as reagent [3] [4] and rediscovered in 2009. [5]
The reaction follows Markovnikov's rule (the hydroxy group will always be added to the more substituted carbon). The oxymercuration part of the reaction involves anti addition of OH group but the demercuration part of the reaction involves free radical mechanism and is not stereospecific, i.e. H and OH may be syn or anti to each other.
