Step by step solution

01

Organocuprate coupling reaction

An organic reaction involves the formation of a new carbon-carbon bond by coupling two moles of an alkyl halide with an organocuprate reagent(R2CuLi) .

02

Synthesising compounds

The given compounds are synthesized as follows:

a. The bromobenzene is treated with lithium and cupric iodide to form the corresponding lithium diphenyl cuprate. This is allowed to react with organo iodide to form the required

compound.

Organocuprate coupling reaction to form substituted benzene

b.Butyl chloride reacts with lithium, followed by cupric iodide to form the lithium dibutyl cuprate that reacts with bromobutene to form the required hydrocarbon.

Organocuprate synthesis of Oct-3-ene.

c. 1-Chloro-3-methyl propane reacts with lithium, followed by cupric iodide to form lithium 3-methyl propane cuprate that reacts with another molecule of 1-chloro-3-methyl propane to form the required hydrocarbon.


Organocuprate synthesis of 3,8-dimethyldecane.

Most popular questions from this chapter

Metathesis reactions can be carried out with two different alkene substrates in one reaction mixture. Depending on the substitution pattern around the C=C, the reaction may lead to one major product or a mixture of many products. For each pair of alkene substrates, draw all metathesis products formed. (Disregard any starting materials that may also be present at equilibrium.) With reference to the three examples, discuss when alkene metathesis with two different alkenes is a synthetically useful reaction.

In addition to organic halides, alkyl tosylates (R'OTs, Section 9.13) also react with organocuprates ( R2CuLi) to form coupling products R-R'. When 2掳 alkyl tosylates are used as starting materials ( R2CHOTs), inversion of the configuration at a stereogenic center results. Keeping this in mind, draw the product formed when each compound is treated with (CH3)2CuLi.

What product is formed in the Suzuki coupling of A and B? This reaction was a key step in the synthesis of losartan, a drug used to treat hypertension.

Draw the structure of the two products of molecular formulaC15H26O2 formed when M is treated with Grubbs catalyst under high-dilution conditions.
