write the following name reactions.??
1). Hunsdicker
2). Frekland
3). Ullman
4) carbile amine
5). Willianmson synthesis
Answers
Answer:
1)The Hunsdiecker Reaction is defined as a chemical reaction which involves in the carboxylic acid silver salts reacting to halogens to create an unstable intermediate that further undergoes decarboxylation thermally leading to the formation of the final product referred to as alkyl halides.
2)The preparation of dialkyl zinc from zinc and alkyl iodide is called the Frankland reaction. Alkyl zinc has found many applications in organic synthesis because because the addition of alkyl zinc to aldehydes in the presence of a chiral catalyst affords secondary alcohols with a high level of enantioselectivity.
3)The Ullmann reaction or Ullmann coupling is a coupling reaction between aryl halides. Traditionally this reaction is effected by copper, but palladium and nickel are also effective catalysts. The reaction is named after Fritz Ullmann.
4)The carbylamine reaction is the synthesis of an isocyanide by the reaction of a primary amine, chloroform, and base. The conversion involves the intermediacy of dichlorocarbene.
5)The Williamson ether synthesis is an organic reaction, forming an ether from an organohalide and a deprotonated alcohol. This reaction was developed by Alexander Williamson in 1850. Typically it involves the reaction of an alkoxide ion with a primary alkyl halide via an SN2 reaction.
