What bromo-substituted compound would be required to react with (CH 2 =CH) 2 CuLi in order to form each of the following compounds? c.

Hello, everyone. In this video, we have defined the halo substituted compounds that were wracked with our organo compound here to give us our desired product, which is in. So what happen is basically that the hali atom will be removed and will be replaced with the R group on the organo coup molecule. So thinking ritual synthetically, our R group of the Organo Cooper molecule is going to be the C H three C H two C H two group. So that will be three total carb compounds that we have to go ahead and eliminate to be using for the Alka Hali to form our product. So going ahead to count these carbons, then we have again, 12 and three coming from the organo cryptic compounds. So you can sort of just break this molecule at that line or bond there. I'm gonna go ahead and draw out our organo coup compound first. So again, we have these three carbons coming from this compound here. Then over to the right then which is of course the al Halide, we have this structure here. We can go ahead and draw in an X. So the X can be any. So it can be bromine chlorine or iodide. We go ahead and draw out each individual possible halos substituted compounded. Again. We said that we can have a bro, we can have a chlorine or it can have a iodide. All right. So these three will be the final answers for this problem. Thank you all so much for watching.

Verified step by step guidance

Step 1: Analyze the target compound provided in the image. The structure shows a branched alkane with a total of six carbon atoms, including a methyl group attached to the second carbon of the main chain.

Step 2: Understand the reaction mechanism. The reagent (CH2=CH)2CuLi is a Gilman reagent, which is commonly used for coupling reactions with alkyl halides. It replaces the halide group with an alkyl group derived from the Gilman reagent.

Step 3: Determine the bromo-substituted compound required. To form the target compound, the Gilman reagent will add a vinyl group (CH2=CH-) to the carbon where the bromine atom is located in the starting material.

Step 4: Identify the position of the vinyl group in the target compound. In the target structure, the vinyl group is attached to the second carbon of the main chain. Therefore, the bromo-substituted compound must have a bromine atom at this position.

Step 5: Write the structure of the required bromo-substituted compound. The starting material should be 2-bromo-3-methylpentane, as the bromine atom is located on the second carbon, allowing the Gilman reagent to replace it with the vinyl group.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Bromo-Substituted Compounds

Bromo-substituted compounds are organic molecules that contain a bromine atom attached to a carbon chain. The presence of the bromine atom makes these compounds reactive, particularly in nucleophilic substitution reactions. Understanding the structure and reactivity of these compounds is crucial for predicting the products of reactions involving them.

Organocuprate Reagents

Organocuprate reagents, such as (CH2=CH)2CuLi, are organometallic compounds that contain a copper atom bonded to an organic group. They are known for their ability to act as nucleophiles in organic reactions, particularly in the addition to electrophiles. Their reactivity allows them to form new carbon-carbon bonds, making them valuable in synthetic organic chemistry.

Nucleophilic Substitution Reactions

Nucleophilic substitution reactions involve the replacement of a leaving group (like bromine) in a molecule with a nucleophile. This type of reaction is fundamental in organic chemistry, as it allows for the transformation of one functional group into another. The mechanism can vary, typically classified as either SN1 or SN2, depending on the structure of the substrate and the conditions of the reaction.
