Interpretation:
The given transformation in the presence of sodium ethoxide is to be explained.
Concept introduction:
Electrophiles are electron deficient species that have positive or partially positive charge. Lewis acids are electrophiles that accept electron pair.
Nucleophiles are electron rich species that has negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair.
Free radical is an atom, molecule, or ion that has an unpaired electron, which makes it highly chemically reactive.
Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.
The carbon-carbon bond forming reaction, useful for the synthesizing of beta keto ester, is known as Claisen condensation reaction.
In Claisen condensation, reaction occur between two esters, a carbon-carbon bond formation takes place which leads to the formation of
Esters containing only one alpha hydrogen do not undergo Claisen condensation reaction.
A Dieckmann condensation is also known as intramolecular Claisen condensation.
Five and six membered rings are easily prepared by Dieckmann condensation.
The rings with members less than five are disfavored due to strain.
