Partial reduction (Lindlar)
Partial reduction (Lindlar) Partial Reduction (Lindlar) Definition: Hydrogenation of the first π bond using the Lindlar catalyst gives cis alkenes. Partial Reduction (Lindlar) Explained: As we know, using a catalyst…
Ozonolysis
Ozonolysis Ozonolysis Definition: Alkynes treated with ozone (O3) will be cleaved at the triple bond to form carboxylic acids. Terminal alkynes give carboxylic acid and carbon dioxide (CO2). Ozonolysis Explained:…
Ozonolysis (Reductive workup)
Ozonolysis (Reductive workup) Ozonolysis Definition: Ozonolysis is reaction where the double bonds of alkenes are cleaved with ozone (O3). Alkanes form organic compounds in which the multiple carbon-carbon bonds have been replaced by a carbonyl…
Ozonolysis (Oxidative workup)
Ozonolysis (Oxidative workup) Ozonolysis (Oxidative workup) Definition: Ozonolysis is reaction where the double bonds of alkenes are cleaved with ozone (O3). Alkanes form compounds in which the multiple carbon-carbon bonds have been replaced by a carbonyl…
Oxymercuration
Oxymercuration Oxymercuration Definition: Alkynes treated with mercury (usually HgSO4) and water will be hydrated to give ketones, via an enol intermediate. Oxymercuration Explained: Hydration of alkynes is similar to the acid-catalyst addition of the water to alkenes, but the…
Oxymercuration [Hg(OAc)2/H2O]
Oxymercuration [Hg(OAc)2/H2O] Oxymercuration (H2O) Definition: Oxymercuration-demercuration is the reaction sequence in which mercuric acetate acts as the reagent. In the first step (oxymercuration), treatment of an alkene with this species in the presence of water…
Oxymercuration [Hg(OAc)2/ROH]
Oxymercuration [Hg(OAc)2/ROH] Oxymercuration (ROH) Definition: Oxymercuration-demercuration is the reaction when alkene treated with mercuric salt [Hg(OAc)2] and alcohol [ROH], and ether is formed. Oxymercuration (ROH) Explained: Mercuration is an electrophilic addition of a…
Oxidative cleavage of vicinal diols
Oxidative cleavage of vicinal diols Oxidative cleavage of vicinal diols Definition: Treatment of vicinal (or 1,2-) diols with an oxidant such as NaIO4, HIO4, or Pb(OAc)4 cleaves carbon-carbon bonds and forms carbonyl compounds. Oxidative cleavage of…
Oxidative Cleavage [KMnO4]
Oxidative Cleavage [KMnO4] Oxidative Cleavage Definition: The oxidative cleavage is the cleavage of the double bond in the alkene by oxidizing agents (such as KMnO4). Here comes to the complete cleavage of the double bond and the chain…
Oxidative cleavage [KMnO4]
Oxidative cleavage [KMnO4] Oxidative cleavage Definition: The oxidative cleavage is the cleavage of the triple bond in the alkyne by an oxidizing agent such as potassium permanganate (KMnO4) which cleave…
