Chapter 20: Q39 (page 809)

Draw the product formed when (CH3CH2CH2CH2)2CuLiis treated with each compound. In some cases, no reaction occurs.

Short Answer

Expert verified

The products formed when (CH3CH2CH2CH2)2CuLi is treated with each compound are shown below:

Step by step solution

01

 Step 1: Use of organocuprate

You can useorganocuprate in many nucleophilic substitution reactions to get products such as aldehydes and ketones.

They attack the electrophilic carbon center of any acid chloride structures where chlorine is a powerful leaving group and also take part in a 1,4-addition reaction.

02

Cases where the reaction is possible

The reaction with organocuprate is possible when the leaving group, like halides, present in acid derivative compounds is facile enough to proceed with the reaction. In case of compound b, no reaction ocuurs.

Besides, the reaction takes place in unsaturated carbonyl compounds where 1,4-addition is possible.

Lithium tri-sec-butylborohydride, also known as L-selectride, is a metal hydride reagent that contains three sec-butyl groups bonded to boron. When this reagent is used to reduce cyclic ketones, one stereoisomer often predominates as product. Explain why the reduction of 4-tert-butylcyclohexanone with L-selectride forms the cis alcohol as the major product.
