Abstract We developed conditions to carry out the first ‘one-pot’ Ullmann-Finkelstein-Ullmann multicomponent reaction reported. This reaction allows the one-pot synthesis of dissymmetrical
The reactions of primary and secondary alcohols with HCl require the presence of a catalyst, ZnCl 2. With tertiary alcohols, the reaction is conducted by simply shaking with concentrated HCl at room temperature. Constant boiling with HBr (48%) is used for preparing alkyl bromide. Good yields of R—I may be obtained by heating alcohols troiodobutane may be prepared either by direct Kornblum reaction of 1,4-diiodobutane with silver nitrite or by a three-step sequence from 1,4-dichlorobutane involving sequential Finkelstein monoio-dination, Kornblum substitution of the iodide by nitrite, and a second Finkelstein substitution of the remaining chlorine. While

Finkelstein Reaction. The Finkelstein reaction is a Substitution Nucleophilic Bimolecular reaction (
Nucleophilic substitution reactions are classified as SN1 and SN2. A SN1 reaction involves a two step reaction mechanism in which a leaving group is lost to form a carbocation intermediate, which is then followed by attack from a weak nucleophile with loss of stereochemistry. A SN2 reaction involves a single step displacement of a leaving group by
The Finkelstein reaction is a Substitution Nucleophilic Bimolecular reaction (S N 2 Reaction) that involves the exchange of halogen atoms.It is named after Hans Finkelstein, a German chemist. It is an organic reaction that uses an alkyl halide exchange into another alkyl halide through a reaction wherein the metal halide salt is used. This reaction takes place in an equilibrium process by

elimination reaction, the halogen (X) is removed from one carbon and a hydrogen is removed from an adjacent carbon and a double bond is formed between the two carbons from which the atoms are eliminated. •The product of an elimination reaction is an alkene. •Two important elimination reactions: E1 and E2.
