Ether Formation [H+/ROH] Ether Formation [H+/ROH] Definition: An acid catalyzed hydro-alkoxy addition is the addition of an alcohol to carbon-carbon double bond to form an ether. Ether Formation Explained: When sulfuric acid is placed in…
Dihydroxylation [OsO4] Dihydroxylation Definition: When an alkene is treated with osmium tetroxide (OsO4), two hydroxyl groups are added to the alkene by cleaving the double bond. This process is called syn dihydroxylation. Dihydroxylation Explained: In this process,…
Dihydroxylation [KMnO4] Dihydroxylation Definition: When treated alkene with potassium permanganate, two hydroxyl groups are added, so the resulting compounds are called dihydroxylates of the reaction of syn-dihydroxylation. Dihydroxylation Explained: In basic conditions, the diol is formed by treating alkene…
Dichlorocyclopropanation Dichloropropanation Definition: Dichloropropanation is a type of cyclopropanation in which two atoms of hydrogen from methylene are replaced by chlorine atoms. Cyclopropanation refers to any chemical process that generated…
Cyclopropanation Cyclopropanation Definition: Cyclopropanation refers to any chemical process which generates cyclopropane rings. Cyclopropanation Explained: Cyclopropanes may be quite readily prepared by the addition of reactive species called carbenes to the double bond of alkenes. In…
Chlorination [Cl2] Chlorination Definition: Halogenation involves the addition of halides, X2 (either Br2 or Cl2) across the double bond of alkenes, giving vicinal dihalides. As an example, consider the chlorination of ethylene to produce dichloroethane: Chlorination…
Bromohydrin formation [Br2/H2O] Bromohydrin Formation Definition: Bromonydrin formation is addition reaction of Br and OH across the alkene and the product is called a bromohydrin (bromo=bromine, hydrin=hydro, water/H2O). Bromohydrin Formation Explained: Lewis acid…
Hydroboration-oxidation is a reaction that converts an alkene to an alcohol. This reaction consists of two parts – hydroboration ( the addition of borane, BH3 to an alkene, forming an alkylborane) and oxidation (converts the C–B bond of the…
